Just wanted to send out a thank-you for your videos on TH-cam! I just finished Organic Chemistry I & II, both with a grade of A! Your videos, as well as other sources too, were extremely helpful!
FOR VISUAL THINKERS: More positively charged ions pull their electrons closer to the nucleus because there are more protons than electrons... ie. more positive charge from a proton per electron orbiting nearby. Vice versa; more negatively charged ions have less pull towards the nucleus per electron, so there are less positively charged protons per electron, drawing their orbit further away from the nucleus.
Professor Organic Chemistry Tutor, thank you for a beautiful introduction into Periodic Trends of the Ionic Radius of Ions in AP/General Chemistry.The rank of decreasing/increasing ionic radii and the size of isoelectric ions are extremely helpful when studying and analyzing this material. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
I understand what is a higher charge in terms of cations (positive ions). For example, Na+ vs Mg2+ Mg2+ has a higher charge (because 2 is greater than 1). But what would be a higher charge in terms of anions (negative ions)? For example, Cl- vs O2- Would Cl- have a greater charge than O2-, because -1 is a greater number than -2?
is there any certain case that is contrast according to your words in the first minutes of this videos? my periodic table doesnt mention any particular radii of each ions
Bro u did mistake in isoelectonic species u said more negatively charged are more bigger but assume (a case 1): Rb+ and F- then Rb+ will be bigger.....Your ans is correct only in same shell😉😉😉
In the second question, why calculating the elector doesn't work? Ca+2 has 18e-, Ga+3 has 28 e-. Ga +3 has more subshell, but why it is not bigger than Ca 2+?
Can you please explain to me why ionic radius decreases across the period from left to right Since anions are larger than cations, why would the ionic radius of a positively charged ion example sodium be larger than that of a negatively charged ion like chlorine. Is it because of the nuclear charge or what?? Or are non-metals an exception to that trend??
anions are larger than cations when comparing it to the parenting of the ion! when moving from left to right the Zeff charge or core charge becomes higher, higher charge means stronger force which means less distance since it pulls in the electrons we know this because of coulombs law.
also as nuclear charge becomes more positive ,effective nuclear charge in creases , thus ionic size decreases but it becomes vice versa with the increase in number of shell
Ions with negative charges are always bigger than the ones with positive charges. The more negative the charge, the bigger the ion. -3 is bigger than -2 which is bigger than -1.... etc.

i now understand life
True..
How?
FOR VISUAL THINKERS:
More positively charged ions pull their electrons closer to the nucleus because there are more protons than electrons... ie. more positive charge from a proton per electron orbiting nearby. Vice versa; more negatively charged ions have less pull towards the nucleus per electron, so there are less positively charged protons per electron, drawing their orbit further away from the nucleus.
i have been finding answers for hours, and this video cleared my thoughts in the first two minutes. Thank you so much!

Thank you so much for this! I was so confused...now I'm not though! Thanks :D
Hats off to you. Your videos are so helpful and you explain so well. Thank you, sir.
I'm preparing for jee advanced this video has very good explanation. Thank you so much.
Hey 'you are awesome by explaining things that are completed . thanks for you help with a lot of respect .
Dude just explained a topic I've been struggling on for months in one video. I lowkey feel so stupid rn, this was so easy.
Wonderful session I was having trouble with this since a long time you made it so simple I’m really grateful to you
Thank you so much for this !!helped me a lot in my assignments...really appreciated🤗
Crystal clear💫❤ thank you😍
Just a powerful explanation.Thank you Gangsta!
All in one without misunderstanding 👏👏👏
Thanks a million for simple clear explaination.
He's 1000000000000 times better than anyone else!!
Seriously BEST CHEMISTRY TEACHER
All thanks to you ❤
I appreciate all your videos thank you. Very helpful.
LOVE your videos
Thanks this helped ALOT❤❤❤❤❤❤❤❤
Thanks, i wish you the best
I understand what is a higher charge in terms of cations (positive ions).
For example, Na+ vs Mg2+
Mg2+ has a higher charge (because 2 is greater than 1).
But what would be a higher charge in terms of anions (negative ions)?
For example, Cl- vs O2-
Would Cl- have a greater charge than O2-, because -1 is a greater number than -2?
Yes (you definitely don’t need this info after 2 years but nobody responded so Yk)
@ ahh no thank you for the confirmation, got an A in my finals this year 😌
From 2022 you make me understand really
I wanna know what ya'll doing now who posted comments 3-7years ago😂
I wanna know what you are doing 😂
lol
Best explaination
10:10 How do we know these ions are isoelectronic with Neon, Ne. Was it supposed to be given in the question?
they have the same electron configuration
Thanks for the help
thanks
Thanks man!
thank you
How to determine picometer?
1 picometer is 10^-12th of a meter or 1 m=10^12 pm!
My question is where does the number for example: CI- (-1.81) < How do you get that number?
Thank you so muchhhh
is there any certain case that is contrast according to your words in the first minutes of this videos? my periodic table doesnt mention any particular radii of each ions
What about Be+ AND B-
There's no love 😭
Very helpful video!!
Bro u did mistake in isoelectonic species u said more negatively charged are more bigger but assume (a case 1): Rb+ and F- then Rb+ will be bigger.....Your ans is correct only in same shell😉😉😉
From up to down it increase and from the right to the left it also increas
Hi, please tell me what program you have prepared for this
It seems like sketch book in windows 10
as we know the IE(ionization energy ) smaller for those with low atomic radi . Does it work in comparing isoelectronic species ?
thanks,😊😊😊😊😊
which is bigger: Cs+ or F- ???
Cs+
@@nevaeh8450 no. cations are positively charged thus smaller. anions are larger than cations.
F-, anions are bigger
@@jamesburmeister1608 no dude that’s only if the parenting ions like the same element
thank kyou
Nothing but love ️(♥️_♥️)...
Unwavering love (♥️_♥️)
Do hydrogen have a similar behaviour ??? The ionic radius of Hydrogen will be smaller than Lithium??
Yes
My teacher described it like a snowman that falls over
I love u sir
how do u find the picometer????????????
Can someone explain why the ionic radius of Mn+2 is greater than Cr+2 ?
In the second question, why calculating the elector doesn't work? Ca+2 has 18e-, Ga+3 has 28 e-. Ga +3 has more subshell, but why it is not bigger than Ca 2+?
because electron increase as you go down and decrease as you go right the periodic table...
@@olaoyemoses2225 yea but don’t we look at distance befoee core charge so don’t ca have less energy levels?
at 6:30 you say k+ has 3 energy levels but isn't it 4?
Can you please explain to me why ionic radius decreases across the period from left to right
Since anions are larger than cations, why would the ionic radius of a positively charged ion example sodium be larger than that of a negatively charged ion like chlorine.
Is it because of the nuclear charge or what??
Or are non-metals an exception to that trend??
anions are larger than cations when comparing it to the parenting of the ion! when moving from left to right the Zeff charge or core charge becomes higher, higher charge means stronger force which means less distance since it pulls in the electrons we know this because of coulombs law.
Life is better now
why does the repulsion happen
When to like charger comes together they just repel
So the same as atomic radius?
Cameron Santiago no, they are not the same
Anion radius is larger than its atom, cation is smaller than its atom
can any explain why o-2 is bigger than f-?
Because the more negative the charge, the bigger the ion.
the more positive the charge, the smaller the ion
What if you have two cation like Na+ and cl+ ?
I had this question in exam and I got really confused.
Thanks for help.
Morning Star for the same period anionic size is much larger than cationic size
also as nuclear charge becomes more positive ,effective nuclear charge in creases , thus ionic size decreases but it becomes vice versa with the increase in number of shell
Ions with negative charges are always bigger than the ones with positive charges. The more negative the charge, the bigger the ion. -3 is bigger than -2 which is bigger than -1.... etc.
cl+ does not exist. cl- is negatively charged, thus anionic, thus larger than a Na+ cation
@@jamesburmeister1608 Cl+ can exist in mass spectrometry
is there a ionic radii table for all ions exist
