1
Q
What does electronegativity mean
A
It’s electrons pulling power
2
Q
If an atom has a greater electronegativity than the other atom what charge will it’s bond polarity be and why?
A
Negative because it pulls the shared electron closer to it
3
Q
Why are shared electrons closer to the smaller atom than the big atom
A
The smaller atom has less nuclear shielding so there is a greater force of attraction between the electrons and the nucleus
4
Q
Why are shared electrons more strongly pulled by the atom with the greater core charge
A
There is a larger charge so a greater force pulling the shared electrons towards the nucleus
