Classify each solid as a covalent, ionic, metallic, or molecular solid? Diamond, frozen carbon dioxide, pure sodium, and sodium sulfide
Diamond possesses a NON-MOLECULAR covalent network.
Sodium exhibits metallic bonding; i.e. positive ions in an electron sea, which gives rise to demonstrable malleability and ductility. (You can deform sodium metal with gloved hands!). Note that sodium, like all metals, is a NON-MOLECULAR material.
And sodium sulfide is also non-molecular, ionic solid composed of individual
