I think you should emphasise that ions become bigger when increasing in electrons because the number of protons stay the same. Kept me confused for a bit before I figured that out.

May the parents that raised you be blessed mahn ❤️❤️❤️I just don't know how to appreciate you . I think if you get paid for this , then am sure what you do is more than what they pay you evn if I don't know how much but this is more than someone working for virtue of being paid

thank you for always saving me in my tests! more power to your channel !

Thank you for that notice on Cation and Anion difference size.... you literally solved one of my 9 wonders of the world (not its 8)

Thank you! I had a hard time understanding the trends of ionic radii but u cleared it up! Thank you for this video!

Wow. So informative! you give me such a relief. sending good vibrations your way!

gotta put x1.5 speed for every one of his vids else i would get like no work done

Hi there! Your videos are great and very educational. It is easy to understand the contents as well. I would like to know the tools you use to make them. I'm trying to start something for the local schools in my area, a tutoring program if I may call it. I want to use a method where I can help as many schools as I possibly can without having to be physically present and I think making videos your method will be most effective. I'd really appreciate your help. Thank you.

Hi! I know this is kind of late - 5 years later, to be exact, but maybe this video might help, since it's a list of his equipment and stuff. kzread.info/dash/bejne/pHaH16-on7C_otY.html

Thanks for the video!!! It helped me clear some doubts🙏🙏👍👍

do you think you have enough adds? you probably could have added 2-3 more...

are there anyone else like me who didn't understand a word on Chemistry class, came to watch a youtube video and then just BOOM, fully understood? I can't be the only one, right ;)

That made so much sense! Thank you so much!!

So atomic radii increases downwards the group and decreases rightwards. But what about the trend in a diagonal direction?

You teach better than all my 8 teachers combined thxs bro

The video is so amazing. actually the contain is so understandable.

Thank you for the clear and concise explanation!

You teach better than my college Professor

were fluorine and chlorine mixed up?

I have a question. Why did you say that P and F have same energy levels when they’re in different periods? Shouldn’t they be P and Cl?

wait so why are atomic and ionic radius so hard to describe?

I love your videos, thank you. Your videos help a lot❤❤❤❤

What about the cations of parent element with different charges?

Great work!!!

Thank you so much! Your video is very helpful. 💙💙💙💙💙💙💙💙

Excellent explaination

That's awesome buddy!

Wow I really enjoyed it Thanks 👍

You are awesome!!!

How to compare the ionic radius of I with a negative bar and S with 2negative bar?

9:15 in cation Na+ isn't the effective charge supposed to be Zeff=10-2=+8 and not Zeff=11-2=+9? Need answers thanks!

@amandesai2990

I'm not entirely sure about this but I think that it is supposed to be Zeff=11-2=+9 because Na+ still has the 11 protons that Na has. The only difference is the number of electrons in the core which changes from 10 in Na to 2 in Na+. So the equation should be Na: Zeff = 11(protons) - 10(core electrons) = +1 and Na+: Zeff = 11(protons) - 2(core electrons) = +9.

nice vid as always.Thankyou!

Thanks a bunch!

saved my chem grades from dropping! bless u

No, I disagree with that Nuclear attraction & Shielding effect both increase down the group, only that effect of the shielding effect outweighs that of the nuclear charge

how you formulated That sodium's Effective charge of nucleus

subtract the number of electrons excluding those in the valence shell from the number of protons

thanks

Is F- smaller than Na+ or larger?

@gabby.k932

larger

@JenJen-ou8ij

F- is larger since its an anion, and anions are larger since the repulsion of electrons increase

You are a star 🙏

i love it

who's the voice behind ths vid?

The explanation of the atomic radius doesn't ryme

Great explanation

This video just made me think of a chemistry joke! But it involves Nitrogen and Oxygen. Do you want to hear it? "N O"

DIFFICULT to understand the DIFFÉRENCE BETWEEN THE 2 OXYGEN AND SODIUM. I DONT SEE THE DIFFÉRENCE.

❤😢

MG is smaller than Al

Good vid but TOO MUCH adds

This makes no sense. You say that when there are more electrons on the outer shell (all else being equal, protons, energy levels, etc.), the radius will be smaller because there are more electrons being attracted inwards towards the protons...but then at 15:25 you say that anions are BIGGER than their neutral version because they have more electrons. Well which one is it??? We can say that more valence electrons - all else being equal - causes a bigger radius because there are more electrons repelling each other and therefore expanding (ie. increasing) the radius BUT we can also say that there are more electrons being attracted to the protons therefore compressing (ie. shrinking) the radius...So which one is it???? Which one takes precedence over the other, the fact that more electrons mean more repelling among themselves or the fact that more electrons mean more attraction towards the protons??? You can argue both! How do we know which takes precedence? This needs to be explained and made clear or else it all seems contradictory......

I think that he didn’t say that when there are more electrons, the radius will be smaller because there are more electrons being attracted inwards towards the protons. He said that when there are more protons, the radius will be smaller because the electrons are attracted more towards the nucleus because the nucleus has a higher positive charge, resulting in the valence electron(s) having a higher effective nuclear charge, which means the electrons are pulled closer toward the nucleus compared to that in an atom with lower effective nuclear charge. That is the trend of the atomic radii. However, for the trend of the ionic radii, the anions are bigger than the parent atoms because they have more electrons, which means there is electron repulsion which causes the electron cloud to expand, making the size bigger.

Terrible video. Wayyyy drawn out for watchtime and way too many ads.

Thanks
