Periodic Trends: Ionic Radius (Ionic Size) | Study Chemistry With Us

[@shaylethornton6123]

So happy I stumbled upon your channel... I can't tell you how much it helped me with stoichiometry (and an A on my midterm!) and now electron configuration and ionic radius all make sense. YOU ARE A GOD SEND! THANK YOU! I don't think I would've made it through the semester without these videos! Will definitely be here all semester next semester for chem 2 and next year for organic chem! Keep em comin!!

Your channel has honestly saved my life!! I was struggling a lot, but the way you explain things is so easy to understand! Thank you so much for all you do! I really appreciate it!

[@GabriellaKogan]

I must say that you are an amazing teacher, I am learning this material in Hebrew and I am just amazed anew how understandable everything is. You're just saving lives with your channel :) Thank you!

Melissa you are a lifesaver. Thank you for these chem videos 😊

[@hectorramirez8531]

First of all, thank you very much for doing this. It's such a huge help when clarifying/learning chem. Something that worked for me when remembering the ionic size trends was keeping in mind the more negative the bigger an anion is. In this example 2- is more negative than 1- therefore 2- it's bigger. Very similarly, +1 is more negative than 2+ therefore 2+ is smaller and +1 being more negative is bigger than 2+. Hopefully, this also helps somebody else.

I loves this study with us videos I learn a lot and thank you for saving my life in chemistry I wished I found your videos back in September

[@hayleysalazar4397]

Thank you once again for making my life easier! My students LOVE you! Your videos just keep getting better and better!

Hi Mrs. Salazar, I'm doing my late work.

[@nicholasachuz8329]

I can't believe that you just asked ,whether it made sense or what whereas you made sure that we comprehend ,i thank you big time

[@chemistryknowsto4875]

You're my hero, you're a great teacher!!

[@katelinkim8706]

Thank you so much this video has been very helpful for my chemistry class! 😄

How I remember the sizes: Small Cat(ion)s make me happy (positive) Big Ants (anions) make me sad (negative)

[@sandeepsinghbhatti4084]

me to ants bite you you feel negative and cats are positive same same :)

[@darcy4522]

You are a brilliant teacher. 😊

[@christinejanellesantos2684]

U really helped me passing may chemistry exam thank you!!! ♥️♥️

[@Teacher2tech]

WOW. Thank you so much. Totally understood this lesson.

[@bidhatatripathi3577]

Thank you so much for these videos. You're an amazing teacher !!

[@agustinjaysoncadag]

You made it easier to understand.

[@chloemacquarrie2054]

You are saving my life rn

[@raineslee8990]

1st Chem exam is today this was so helpful!!

[@krait05]

This really helped me lot😁😁 , i wasn't able to understand it from my own teacher 😅 Thank you 9u ma'am 😀

[@norshahilaismail1688]

thanks.I have first test this saturday.And like usual u came to the rescue

[@abigailescobarvillagra7089]

i will be forever grateful for your help

[@jamieevans7322]

Trying to finish Chemistry class with not having to retake. I think its alot harder than in person! Thanks for all your help. Teacher doesnt lecture so I am really unsupported. Use a tutor but only 2-3 hours a week

[@nobodysuiii]

better than my uni instructor

[@ChemicalAdventures-Echi]

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??

[@shjmm192]

thank you soooooooo much, ur the best

[@mariamalkaabi4886]

thank u!

[@angeloastudillo8001]

THANK YOU VERY MUUUUCCCHHHJJ

[@jchiakik]

Could you direct/link me to the video that explains how Ga became Ga^3+???

[@unnamedcharacter9065]

Do you mean for the example at 6:19? it is explained at that timestamp

[@jchiakik]

@@unnamedcharacter9065 I actually needed to know (or be reminded) how it came to be GA 3+, finding the net charge, but I found a video and I facepalmed right after. 👍🏻

[@kathirenecarillo6039]

Thank u so much this helped a lot t.t

[@aniavanessian3385]

I am a bit confused on how the Indium cation has a smaller radius than the Bromine anion if the Indium cation has 48 electrons and is in the 5th period versus the Bromine anion which has 36 electrons and is in the 3th period.

[@kaka_y_donas9129]

This is so funny and frustrating because why do I need to know this😭 but anyways thank you for making these videos 😊😁
