Re: ionic radii

As the people above said, cations are larger than the neutral atoms because there are more electrons that are pushing against each other and expanding the radios. The atomic radius of neutral elements decreases across a period because there are also increasing amounts of protons pulling in the elect...

Re: Mini Dino Nuggets 2b

Fluorine is the most electronegative element, and therefore the bond with F would be more ionic.

Re: Electron Negativity vs affinity?

I believe electronegativity is a measure of how much an atom "wants" to gain an electron, whereas electron affinity is a measure of the amount of energy released when it does gain an electron.
