Question

I'm not sure about this: Rank from most to least valence electrons- Xe, In, I, Sb, Rb

Thanks

Answer 1

If we define "valence electrons" as simply the number of electrons in the outer shell of an atom, these can be found in the periodic table. Xe has 8, Rb has 1, I is 7, etc. Just look up the electron configuration of each.
