Isoelectric Atomic Radii

Postby Sophia Diaz - Dis 1B » Sun May 06, 2018 11:10 am

Hi guys! So I remember in class going over isoelectric atoms, but I don't really get why they are not the same size? If they have the same amount of electrons, doesn't that mean they should all be relativity the same size?

Even if the atoms have the same amount of electrons, you still follow the trend for atomic radii.

Just to elaborate on the trend, atomic radii increases as you go down and to the left of the periodic table. For example, look at homework #2.59

Even though isoelectronic "ions" have same number of electrons, the number of protons may differ for those ions/atoms. So the ones with more proton will "pull" on these electrons more, giving smaller radius.
