6
Q
Bond angles
A
Idealized angle for the molecular shape
7
Q
Lone pairs
A
Repel more and decrease the angle between the bonding pairs
8
Q
Double bonds
A
Has greater electron density than a single bond, also repels more than single bond electrons
9
Q
Most to least repelling electrons
A
Lone pair> triple bond> double bond> single bond
10
Q
VSPER
A
Each group of valence electrons around a central atom is located as far as possible from the others to minimize repulsions
