1
Q
electronegativity
A
measure of how strongly atoms attract new bonding electrons to themselves
2
Q
octet rule
A
atoms want to obtain a full outer shell in order to be stable
3
Q
would Li or O have a higher EN
A
O, its further to the right
4
Q
Why does the EN increase as you move to the right on periodic table?
A
the protons increase as you go from left to right
5
Q
Does Ca or Ra have higher EN
A
Ca, its further UP
6
Q
Why does EN get weaker as you move down periodic table
A
as you go down, the valence electrons go in a higher energy level, increasing the distance.
