A
107 degrees, 3 bonded pairs (1 lone pair)
3
Q
non-linear
A
104.5 degrees, 2 bonded pairs, 2 lone pairs
4
Q
linear
A
180 degrees, 2 bonded pairs
5
Q
trigonal planar
A
120 degrees, 3 bonded pairs
6
Q
octahedral
A
90 degrees, 6 bonded pairs
7
Q
lone pair
A
a lone pair of electrons is closer to the central atom and therefore repels more strongly than a bonded pair. it reduces the angle by 2.5 degrees.
