Trends in the Periodic Table

Across the periodic table, we can elucidate trends (patterns) in atomic properties. In this video, we examine trends for three properties: atomic radius, ionization energy, and electronegativity.

[@annethara]

I absolutely loved the illustrations of the periodic table with dots. It made things a lot easier and convenient to understand. Thank you so much for this!

[@duellchemistry]

I’m very glad you liked it! Thank you.

Bannderson _ how are they a simp?

[@lake_pond1567]

I think they believe that any form of thanks is simping. They are confused because they have never been thanked for anything so they have no form of reference

[@ranjithsivanandham1927]

Even me

[@alexcope4144]

Rewatched my lectures and re-rea my book several times and it made it overcomplicated. Light bulb moment when you said that the other trends followed the first. Makes so much sense now, thank you!

[@duellchemistry]

Yes!

[@belenrodriguez2566]

[@clubanimations1151]

I have a question. Is the reason that the attraction of nucleus subdues the repulsion of electrons because nucleus are concentrated and confined in one space, while electrons are scattered around more singularly?

Yes

[@morganm7656]

when you are saying that the radius is smaller from left to right is that because s effective is stronger from left to right? is that what you are saying with "pulled tightly together" ?? thank you so much for this video!!

[@nebbetta597]

VERY helpful!!

[@AngelikaUy]

Hi! What app do you use for your animation? I'm a teacher and I'd like to learn how to make my presentation less boring.

[@duellchemistry]

Hi Angelika. Making your presentations less boring is a noble pursuit. Your viewers will appreciate it! I use Apple’s Keynote app on a MacBook Pro to make my animations. I record with Screenflow (which records my face, voice, and screen all at once) and then I can do some screen zooming in the editing phase too. I hope this helps. Good luck!

[@gabbycamacho4878]

🎯 Key Takeaways for quick navigation: 00:03 Atomic *radius increases from top to bottom within a group on the periodic table, explained by the addition of electron shells. The snowman analogy helps visualize this trend.* 02:09 Within *a period, atomic radius decreases from left to right due to increased nuclear attraction as protons and electrons are added.* 05:22 Ionization *energy increases from left to right across a period, as smaller atoms hold electrons more tightly. In a group, ionization energy decreases from top to bottom, where larger atoms make it easier to remove electrons.* 08:33 Electronegativity *increases from left to right within a period on the periodic table, and it decreases from top to bottom within a group. This trend is influenced by the atom's size and its ability to attract electrons.* Made with HARPA AI

How do you know which element has greater atomic size based on the trend if they are closely the same in size but different in group and period like beryllium and aluminum? Magnesium and Gallium? Thanks for the response.
