Gallium Nitride (GaN)

Covalent Bond!

Atomic hybrid orbitals: sp3

sp3 Hybrids. The top four images show the four sp3 hybrids.

These particular sp3 hybrids are combinations of 2s and three 2p functions.

The bottom shows the relative positions of these four hybrids superimposed.

Note that in each case, the nucleus is embedded in the minor lobe.
