Answer 1

Answer #1

Part 1. The unit cell of graphite can be drawn as follows.

The no. of carbon-atoms in unit cell = 15

Bu the no. of carbon-atoms per unit cell = 6 (hexagonal lattice)

Part 4. The coordination number of carbon atoms in graphite = 3

Part 5. The hybridization of carbon in graphite is sp².

Part 6. The atomic packing factor of (APF) of graphite (Hexagonal Close-Packed structure, HCP) = 0.74
