molecular shapes depends on
the number of pairs of electrons in the outer shell of a central atom
1 of 7
electron pairs are
negatively charged so will repel each other
2 of 7
put these bond angles in order of increasing size
bond pair- bond pair, bond pair- lone pair, lone pair- lone pair
3 of 7
tetrahedral molecules, with no lone pairs, have a bond angle of
109.5
4 of 7
Boron trichloride, BCl3, is
planar with a bond angle of 120°
5 of 7
The HNH bond angle in ammonia is
107°
6 of 7
The shape of an ammonia molecule is:
pyramidal with four electron pairs around the nitrogen atom
