How are the atoms shown in the atomic-scale models different from actual atoms

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.
