Actually.. We calculate Van der Waals radius for Noble Gases and they have the highest radius in their period.. So answer to the first question is Fl>Pb>Kr>Ge>Br.. Hence answer given in this video is wrong..
I’m saying though cause he started from the right when you posed to start from the left as work across so it decreases, and as you go down it increases.
3:00 But aren't the noble gases supposed to have greatest atomic radii in their respective periods due to their non-bonding nature vanderwaal forces between them? Then the order would be Br
When comparing ionic radius, you gave us a best/easiest case scenario where all elements have both the same # of electrons and the same energy level, well then of course the only remaining factor is the # of protons. What about when there are also different amounts of electrons and different energy levels? How do we then determine ionic radius if we have 3 things to consider: amount of electrons (more = bigger radius due to electron repulsion), energy levels (more = bigger radius), protons (more = smaller radius due to proton-electron attraction)...I'm trying to figure this out for Chem 11...
Professor dave, you know what i love from every video of yours? I really love the way which music is like "he does know about science and stuff professor dave explains!" At beginning of every video. Woow it sounds cool man hahaha xDDDD You did a great job on music part, it gives excitement such that even a sleepy person can wake up by that music. Nice way of waking up people with that music.
i’m am literally taking the highest path of education that you can for highschool in my area and yet my chen teacher has seemingly forgotten how to teach! These are the only things actually teaching me anything about this subject! I wish I had found you sooner!
I have a question, we all have studied that : Vanderwall radius> covalent radius. So Ne has Vanderwall force between them right? So it must be 'kr' which should be the largest in this question, but idk why kr isn't the biggest, can you plz tell me why?
Radius has nothing to do with reactivity, it's just about the number of protons in the nucleus and the number of shells. Neon has one more proton than fluorine.
Love from India ❤️♥️😍😍

Yes bro y are ryt

Still waiting for the answer too
Thanks sir ❤️❤️ love from india 🇮🇳🇮🇳
thankyou so much!!! helped me a lot........from INDIA!!!!!!
Thank sir...love from India ❤

Thank you! Very helpful compared to some other videos
Best lecture ever
Is ionic radii of metals less than their atomic radii?
Yes since metals have tendency to give electrons, same nuclear charge lesser number of atoms results in ionic radii being smaller than atomic one
But what if electrons number is also different ?
Thanks for this video...
Make a video that why Gold is costly and found rare... (kindly explain based on Pure Chemistry, no historical tales)
Really helpful 👍🏻
been watching all these cause my final is tomorrow at 8 am and I haven't went to class half the year

this question is not discussing any intermolecular forces, it's just about atomic/ionic radius.
@@ProfessorDaveExplains oh ok, it means, its just for one atom!
Nice explanation sir .Tq sir
The stats of the channel is really making me sad😪
tell your friends to watch and subscribe!
Mr. Dave I believe is the way you spoke. As well as your face not present in the video
Love from nepal 🇳🇵🇳🇵
Sir, how can we find atomic radius.
Dude you saved my life
Why neon is not the largest as it is a noble gas??
radius contracts moving right along a period
@@ProfessorDaveExplains Thanks a lot sir....
Radius has nothing to do with reactivity, it's just about the number of protons in the nucleus and the number of shells. Neon has one more proton than fluorine.
Kr has noble gas configuration which have vander wall radius so kr has largest atomic radius not germanium please tell. Me Dave
Aren’t the noble gases actually larger?
Sir, why is kr not the largest cuz vwf
What is nature of ionic radii
'Kr' Should have the largest radius in Question 1.
Um, no. It's the smallest.
Love from somalia ❤
for the record my college-level chemistry class referenced this video
thank u sir
My teacher told that neon will be largest because it is noble gas
well your teacher is wrong.
But why
The more protons an atom has the more attraction it will have to the nucleus so it will be smaller
Love you
Damn you really are something, Ufff💪🏻🔥
Op bolte zandu
Sir walaa🤣🤣
Kr lesser than Br..🙄🙄🙄I thought it's second largest in its period after K
radius contracts moving right along a period
Please speak in english
