Crystals???

Question

What type of crystal is lithium fluoride, carbon tetrachloride, sodium, and silicon carbide?

Answer 1

Lithium fluoride, like Sodium chloride has cubic crystals.

Carbon tetrachloride is a liquid at room temperature. If cooled below -22.9 °C it would probably form monoclinic crystals like Carbon tetraiodide does.

Sodium is an alkali metal. Metals usually do not have a crystaline form.

Silicon carbide has two different crystaline forms: Alpha is hexagonal and Beta is face-centered cubic.
