Graphite+tape=Nobel Prize for Physics.
+almostfm give me another molecule like graphite and I'll share the Nobel Prize money with you.
almostfm chemistry
Samovar maker you dont get money for winning a nobel prize
yes you do
Unfair.
Carbon: "And this isn't even my final form...!"

This video has blown my mind! I had no idea carbon could form so many different structures.
I just realised that his tie is the periodic table, I adore this man so much! This whole series is so informative and wholesome I want to cry with joy!
Mady; Take a look at the clock on the wall just to the right of Martyn's heat at 4:51 of this video. The time is almost Nitrogen past Lithium!
Carbon is probably my favourite simply due to the sheer variety of compounds you can make with it. Also, drawing organic compound is fun.
absolutely LOVE these videos.. they always help me before my science exams. these concepts get clear because you can visualize it with the help of these videos
From what I remember from a brief attempt at chemistry, one of the funny things of buckyballs/fullerenes was that adding a group to one point of the ball, changed the energy (and usually making it easier) to add the group to the next position. Basically you got only a few products, all 60 positions reacted, or none at all. (or slightly less when there was steric hindrance)
I cannot thank you enough for this video. You are the first of about five videos that I've watched that explained carbon in a manner that was attainable thorough simplistic and helpful.
I wanna go to that school!
University not a school.
@@patrickmoloney672 lol a university is a school smarty pants :)
I feel you

Thank you for these discussions. It's a real opportunity to get some chemistry lessons and experiments when taking courses isn't an option.
Oh Carbon, we love you
Wait his tie has the periodic table on it?
Lord Pain yeah isnt that cool?
That has always been there. It is like one of his body parts. yet he gives his away occasionally if someone admires it during any lectures of his
First time watching one of these videos? He has an extensive collection of "elemental" ties. They're actually kind of amazing.
he has alot of ties with all sorts of designs and periodic tables on them
I want to take a suitcase full of carbon models to the airport to observe the reaction of the baggage people.
"We uh... seem to be detecting a large amount of diamonds in there..."
Their ‘reaction’ XD lol
@@MrSonny6155 haha
I'll bring a bag full of meth (C10H15N
) that will act as a catalyst for my chances of getting arrested.
When you have hair like that, everyone just assumes you're a scientist. They'd probably get suspicious if his bag DIDN'T contain any weird-looking gadgets.
If they made videos one hour for each element, I would also watch all of them. Since I was a child I always wanted to know everything about elements and their chemistry. Totally fascinating
My favourite part of chemistry is naming organic compounds. I find that very fun!
Carbon says: THIS ISN'T EVEN MY FINAL FORM!
Lol
These videos are awesome! Thank you for taking the time to make a video for each element and not just one for the whole PT. It's super interesting and I'm really inspired by your dedication!
These videos are so concise and explain everything so well that it blows my mind every time i watch one.
Really like the videos! I'm an undergraduate Computer Science student, but still love these videos! They spark my imagination and make me want to take a few Chemistry classes! I often think of Chemistry as the study of programming nature, and got to thinking about it, and was wondering how a Chemist thinks of Computer Science?
6:25 Does that imply that no material that's clear (due to the electrons being tightly bound) can ever be a decent conductor of electricity?
basically yes, considering electricity is the transfer of electrons, if something has strong bonds it is less likely if if not unwilling to give up electrons ..
Indium tin oxide (ITO) is a clear conductor.
The electrons may deal with non-visible light. That would cause a clear conductor.
@@abhayshankar8762 Thats kinda what I was thinking, actually. Thanks
No. It is just a rough explanation of why diamonds are transparent (because there are no electrons that can be excited by visible radiation). However there are plenty of clear/ colourless/ transparent substances with electrons in double bonds and other structures that might absorb light but they absorb in the UV eg perspex.
I learn so much from your videos. Love them!
This is one of the most interesting videos i've seen in months!
I love the new electron miscroskope images your showing usw... amazing how the molecules actually look exactly like the models you see at school when you take a close look at them in the scope... sounds stupid, but that kind of amazes me...
Interesting video on Carbon.. What a coincidence I happened to see this today! Only yesterday I was teaching a local school children on Carbon different forms as per their curriculum. Nothing will make the topic clearer than seeing this video!1 Today ia hope to show this to them. Great work by Martyn to young generations , possible future Noble Laureattes.
G for graphite, A for awesome!
My pills are that big lol
He didn't mention the use of Carbon to make steel. If you add 0.4% carbon to pure iron, you get a much harder, stronger metal which we call steel. Actually, there are hundreds of different alloys of steel that have other elements added. Maybe he mentions this in his video about Iron.
Wei Zhao steel isnt a metal? Uhh yea dude steel is metallic i think you mean its not an element
Outstanding Professor, great contribution to young Chemistry students understanding of elements. Dr Gopalan FRSC
Love the dedication in revisiting all the elements. Plus, given the acclaim you've recieved for the series, sure you can get access to more resources.
Thank you Professor, really helped me.
The train-truck analogy made things really clear, thanks for that!
1:20 carboner
I just love the Professors box of tricks, its amazing!!
This video is a masterpiece! Really thanks for sharing the precious knowledge!
Holly molly love the videos, beautifully explained.... that dude explaining now has a fan... Thanks.
Great video. I was as much intrigued by the water bottle collection(?) as the carbon content.
Excellent educational video. Well done.
@Noovil25 you see the color that it didn't absorb. The color it reflects. The best example ist if you look at dichromatic mirrors (or short "dichro") widely used in laser applications. They only reflect one certain color, so they look like the color they reflect. The light they let through, is "the rest" which was not reflected.
"It's been discovered in the last ten years that using a piece of sellotape..."
I love that!
these are the best videos ever!!! thank you :) you are helping me like science!
Carbon has a huge amount of information and uses. He hasn't talked about its hybridized sp orbitals, 2s2 2p2 electrons have 4 electrons in hybridized sp orbitals. Are these talks about inorganic and not about organic chemistry? But buckyballs were covered in organic chemistry textbooks, too.
Thanks for all the Videos!
Wow... thank you for this video! You've answered many of my questions with it :)
oh my god, i love these videos way too much
I call it purple, other people call it Magenta :D :'D
Lilac
👍😎😂
Or mauve
Lavender?
Violet
Nice clock i am going to use the same in my room too. Really you are a genius. We have learnt a lot from you.
Amazing guys. :D!
Could you make a video about some alkaloids in the molecular videos section?
Boyle is one of my favorites. You can change what temp things freeze at or turn into gas or even plasma just by changing the pressure of the air. I think one of the gases close to neon does something cool if you give it less then normal air pressure, it turns into plasma if you electrify it. Sure water crystalizes at 32F so you think of coldness when you think of freezing but other things can freeze and crystalize at room temperature or even higher
The relative conductivity of various forms of carbon was quite interesting.
I´m exited because I recently started my first course of chemistry it´s awesome.
Love the periodic clock in the background.
Do you get it? The elements atomic number represent the time. lol So H is 1, He is 2 etc.
Rob Porritt lol they have one in the chemistry lab at my school
Who remembers the Star Trek movie, where the ...villain robot (V'ger) refers to the humans as "Carbon Units" ? Hahahahaha ! Dear Professor, and the rest of the Team, thank you so much for this excellent video. One of your best.
I would love tk see a video on Teflon. The only molecule thst can contain Fluroantimetic acid.
Brilliant piece !
I've never thought before why diamond is transparent. Now I understand it clearly. Once we are able to manufacture sheets of it, how effective would a window made from diamond be?
Thanks for this video :D in chemistry class where learning about allotrope's of carbon and covalent networks, this helped me understand it a lot :D
amazing video. i learnt a lot from this video alone...
@pawningcity
C60/70 are discrete molecules. The solvent can move around between the individual molecules and interact with them, which allows them to dissolve.
In something like graphite/diamond you have big huge sheets/structures of carbon, these wont dissolve simply because the structures are so large the solvent cant get in between to break anything up.
Love the clock!
Oh my god I need that element clock in the background :D
Oraganic chemistry was my favourite subject in high school. Carbon is a fascinating element.
When he said he had an suitcase of models I did not expect a literal suitcase. I love these early videos
Something really want to ask:
Silicon is in the same group of carbon, or other elements in that group as well. Why can't those elements also form these wide variety of molecule chains? just like the way carbon does? Especially for silicon regarding its huge abundance
Because Silcon-Silicon bonds are not as strong as Carbon-Carbon bonds. The reason for this is that the Silicon atoms are larger than Carbon atoms, so their electrons are a greater distance from the nucleus and require less energy to break. You can have chains of Silicon atoms, but they are limited to about seven atoms long before they become unstable.

thanks a lot for the piece of information!
You're welcome :)
i think it's due to its reactivity and larger size. Other atoms can interact with silicon atom through its d-orbitals which makes silicon atom more susceptible to nucleophilic reactions whereas carbon is more stable, especially if it is tetra-substituted.
Silicon can catenate (form long chains), however not as easily as carbon and the reason is carbon has a smaller atomic radius and the same shielding effect on its valence shell of electrons. Hence, carbon has a higher electronegativity and can more easily form the covalent bonds required to form these long chains. Silicon can as well, but the chains formed by carbon are far more stable because of its higher electronegativity, resulting from its smaller atomic radius.
Interesting stuff. Easily understood too. I wonder when we will see graphine in a common application.
Loved ur periodic table tie
Carbon is such an exciting element!
Science is the only place where saying "he gave me a whole suitcase of models!" means something else entirely
I can't wait for the time where carbonnanotubes, graphene and C60 can be made on a large (industrial) scale. This will be a revolution in electronics.
That conductivity demonstration was mind-blowing O:
in a hexagonal carbon ring, can each carbon atom form a molecular bond with another element, and if so, than how many electrons does each atom need to fill outer electron shell?
4:35 You've cheered up my mourning !
Carbon is such a fascinating element. Especially because it can create intelligent thinking matter like you and me.
@giltine002 You have a point there... i hadn't even thought about that.
About the mesomeric structures you are partly right,but you should look at it more like delocalized bonds. They can be delocalized in a way that forms a C=C bond for a short amount of time, but that is rather improbable. They way our teacher wanted us to look at it was like 1 1/2 bond between carbon atoms. But since you made your point, i'm unsure if my theory is right because the rings are not really defined.
omg i love the models that he has!
guy is awesome. Wish i had someone as smart as him teaching me when i grew up
Wow, such a simple explanation of why things are conductive and not, at the end.
I just love that the Professor has a suitcase full of carbon models. I want one.
Pure graphene has much better conductivity than metal though.
Graphene is awesome!!!!!
A fair comparison would be with a monocrystalline metal sheet, since graphene is a single molecule sheet. Really curious about this comparison.
I got enthusiastic knowing the electrical conductivity, carbon nanotubes, it seems that there is a bright future for this :D
Look at his clock! 5:58 He sure loves the elements 😉
Yeah
"you're carbon, I'm carbon"
I can just imagine going to an AA meeting where everybody has a nametag "Hi, my name is Carbon"
I hate how these videos just end! Each one should be an hour minimum ;)
@TheErraticTheory They are called molymods. I suppose you could google it to find out where to buy it
Amazing video sir
Very interesting. Thank you. How would graphene perform in the conductivity test at the end?
nice name
Thanks for posting!
loved this video :)
don't know why C-50 wasn't mentioned. i discussed this cool video on my enviroblog the other day, see the Hazard Hot Sheet, the post titled "The Sixth Element," for the tip of the hat. i love u guys! wish i could win a Nobel with some tape.
what happens on the surface of diamond? How does the carbon bonding end off?
Hydrogen and oxygen typically bond to the surface of the diamond.
Oxygen and hydrogen bond typically to the diamond's surface
do you know where is carbon found like in which country
@@winter4505 Depends on the form (allotrope) Many countries have Coal, Anthracite is probably the purest form of carbon that is a coal type. Africa and some other countries have Diamond, it occurs in ancient volcanic pipes in a rock type called kimberlite. Graphite occurs in metamorphic rocks, thus it too will be associated with igneous rocks to some extent as it is the presence of such along with the heat and pressure that causes the alteration of carbon into graphite, not sure exactly how but google will pull that one up.
That slime of carbon is so satisfying to watch
Capacity might not be the right word, but the unprecedented capability of any organism to produce fine chemicals is indeed amazing. Even more so given that organisms have only a limited supply of catalysts and reagents, and yet they can always make them. Of course when one considers the 4.3 or so thousand million years of evolution that have lead to this, it becomes a little less impressive, but nevertheless still immensely amazing.
thats a cool clock in the background :-) anions and cation
Great videos thankyou
Nice, love it!
Is that a black and white drawing/artwork of Sri lankan/Kandyan Perahara left to the clock..?
BTW, I'm binge watching the whole playlist of periodic table this time.
I'm very hopeful of breakthroughs concerning graphene in the near future. Carbon has so much significance in our lives, yet only up until now scientists have started unlocking its full potential. I'm glad to have been born in this day and age.
on the topic of the comparison of carbon to a train and its analogy to a bus ... would that depend on the analogous train tracks and the speed ?
What type of bonds are in between the layers of graphite? (Represented in purple in the model)
1:45 Maitotoxin, good choice. Guess I'll never forget about that one.
Also, about the purple bonds in the graphite model...what's the difference between them and the bonds inside each sheet? (well, except for the fact that they are less strong)
