| Gallium (Ga) | |
| Atomic Number | 31 |
| Atomic Weight | 69.72 |
| Room Temperature Structure | alpha-Ga (A11) |

The s and p tight-binding parameters were fit to first-principles Linearized Augmented Plane Wave (LAPW) results. The d orbitals were excluded from the fit. The following ranges were used:
| Structure | Minimum Range Lattice Constant (Bohr) | Maximum Range Lattice Constant (Bohr) |
| fcc (A1) | 7.40 | 8.20 |
| bcc (A2) | 5.80 | 6.80 |
| simple cubic (Ah) | 4.70 | 5.50 |
| Reference | Phys. Rev. B 57, R2013-6 (1998) | |
Use of the parameters outside of these ranges may result in unphysical behavior.
