Electronegativity and stability of ions?
Second one, If you have a larger size anion, you have a larger volume, and the electrons are spread over a larger space (less repulsion) so it is more stable. I can't give a clear answer for the first point, because my teacher as I said previously gave me a pizza analogy..

i was explained it in terms of charge concentration. such as, a small, highly charged ion such as say, aluminum is reactive, while a big, less charged ion like iodide is less reactive.
however when i think about it in this way there's alot of exceptions, such as the NH2- anion, which is big, but much more reactive than F-, which is smaller.

Ok. Thank you.
Any idea about the stability tendency along the period?
