In some exams, a template of the periodic table is not provided, so students are thought have to identify a metal and non mental from their electronic configurations
Thanks for this, I've seen another approach to identifying the type of chemical bond in a compound apart from electronic configuration. I will introduce this approach in my lessons Aluminum chloride is covalent, as you said, in chemistry there are exceptions to rules
Great question! I don't have a great answer, but it has something to do with the fact that carbon has 4 valence electrons and 4 hydrogen atoms (each with one valence electron) perfectly allow for covalent bonding. My better answer is that there's always exceptions in chemistry, and you just found one of those exceptions.
How about if I you were asked the bonding of two elements that were both on the left side, for example Ca and V, or the bonding of two elements on the right side, for example Cl and O. What would the answers be for these
I'll be honest, I've never seen bonding between two left side elements (I might be forgetting something obvious), but I'm guessing that would be covalent bonding. For two right side elements, that's actually very common, and that will always be covalent bonding.
That’s really complicated. Take H2SO4 for instance. The H has an ionic bond with SO4, but SO4 is made of covalent bonds. And there’s millions of different combinations of elements. So there’s a lot of rules.
Hydrogen is a special case. Even though it's on the left side, it can be part of ionic or covalent bonds depending on the other elements it is bonding with.
This is a rare exception to the rule. Beryllium and fluorine are ionic bond, but Beryllium and Chlorine/Bromine are covalent. Not sure why nature had to do this to us, but we have to live with it.
It has to do with a concept called electronegativity. Every element has an electronegativity value, and when the electronegativity values are similar, the elements form a covalent bond. And when the values are starkly different, they form an ionic bond.
Hydrogen is a special case. It can be both ionic or covalent depending on what it's bonded to. It would take me a while to talk about all the hydrogen cases.
because there's always exceptions to the rule in chemistry. There is a reason why, but I would just recommend memorizing that one. It's a pretty famous example.
On making it s structure due to dipole moment from H to N from 3 direction of tetrahedral it's net resultant gets add up in the direction of lone pair .
Thank you so much for simple explanation everything is easy and clear you the best 🎉
Always happy to help!
My exam is in an hour and this video helped me so much with studying this lesson (I’ve been struggling in it for days) thank you so much god bless you
Always happy to help! Good luck!
I wonder why teachers did not explain that way to us🤣.
I now understand ❤️💯
Some teachers like to watch you struggle, haha

You are a good tutor Dan
I'm not "good", I'm the best! Thanks
Thank you! This video was very helpful. I really appreciate your effort to make this video
the apple doesn't far fall from the tree but your video is a tree in the apple dimension
Thank you so much, for the explanation. It was so easy and well made!!!!!
Thanks! Always happy to help!
Questio! What about when 3 elements are bonded together? And thank you for the video, it was very helpful.
It depends on the specific example. Also if there’s a compound present.
THANK YOU SO MUCH!!
I havemy summative assessment on Thursay and this tips are going to help me so much 😭💗
Happy to help!
Thank you sooooo much sir.This video qas soooo much helpful
Thanks! Always happy to help!
Thank you!
Happy to help!
you earned a sub🙏keep up the good work

Aluminum chloride is covalent, as you said, in chemistry there are exceptions to rules
Happy to help! This has always been my preferred method.
good video!
Sir how we find out co-ordinates bond is there in compound
Great explanation! Question: why is carbon-hydrogen bond considered covalent (considering that Hydrogen is on the left?)
Great question! I don't have a great answer, but it has something to do with the fact that carbon has 4 valence electrons and 4 hydrogen atoms (each with one valence electron) perfectly allow for covalent bonding.
My better answer is that there's always exceptions in chemistry, and you just found one of those exceptions.
Thank you sir! u saved my time
Tell your time I said you’re welcome

Song?
Thank you sir now everything is clear 😁
Glad to hear it!
Can you make a video about how to draw compounds with covalent bonds and then how to determine overall polarity and the shapes?
Sure! But it probably won't be done for a while. If you're looking for something right now, here you go. th-cam.com/video/OHFGXfWB_r4/w-d-xo.html
hello, what about 2H --> O?
That’s covalent (even though it breaks the rule)
what if you have three molecules and two are on the right and ones on the left?
That’s really complicated. Take H2SO4 for instance. The H has an ionic bond with SO4, but SO4 is made of covalent bonds. And there’s millions of different combinations of elements. So there’s a lot of rules.
Thanks . It helps alot
Happy to help!
isnt a bond from 2 elements on the left side called metallic bonding?
I think that's right
What about AgCN? Is it covalent or ionic?
That would be covalent, but it’s an exception to the normal rule.
Hi is hydrogen part of the right side
Hydrogen is a special case. Even though it's on the left side, it can be part of ionic or covalent bonds depending on the other elements it is bonding with.
What about AlCl3
Covalent (it’s an exception to the rule)
sir, what about beryllium and chlorine why are they covalent bond
This is a rare exception to the rule. Beryllium and fluorine are ionic bond, but Beryllium and Chlorine/Bromine are covalent. Not sure why nature had to do this to us, but we have to live with it.
This is a great trick to remember but I want to understand why this is the case
It has to do with a concept called electronegativity. Every element has an electronegativity value, and when the electronegativity values are similar, the elements form a covalent bond. And when the values are starkly different, they form an ionic bond.
Where does hydrogen fit in this scheme ? (Hydrocarbons utilise covalent bonds.)
Hydrogen is a special case. It can be both ionic or covalent depending on what it's bonded to. It would take me a while to talk about all the hydrogen cases.
But a doubt what if it was like O3 or O2 or H2
All of those are covalent. A general rule of thumb is that if you are bonding 2 or more of the same element, it is going to be covalent.
What about water H2O? Isn't that covalent bond?
Yep, H2O is covalent. Even though H is on the left side, Hydrogen is famous for being able to do both ionic and covalent bonds.
Then why NH3 is covalent instead of ionic 🥹
because there's always exceptions to the rule in chemistry. There is a reason why, but I would just recommend memorizing that one. It's a pretty famous example.
On making it s structure due to dipole moment from H to N from 3 direction of tetrahedral it's net resultant gets add up in the direction of lone pair .
@@AIMFORNEET-qc9jd if the dipole moment direction is added towards the lone pair then it we will say it will be a covalent !?
Can you explain better
No, this is the best I’ve got
