# Classify each solid as a covalent, ionic, metallic, or molecular solid? Diamond, frozen carbon dioxide, pure sodium, and sodium sulfide

$C {O}_{2} \left(s\right)$ is molecular, with the individual molecules held together by (weak) dispersion forces.
And sodium sulfide is also non-molecular, ionic solid composed of individual $2 \times N {a}^{+}$ and ${S}^{2 -}$ ions held together by strong electrostatic interaction between the positive and negative ions.
