crystal compounds
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.
Potassium oxide (K2O) is an ionic compound, not a molecule, and does not have a Lewis structure.
There are distinct molecules in in substances that form an ionic compound, it is just that when they form an ionic compound (a crystal lattice structure) the pattern in the sturcture is the dominant feature rather than separate molecules.
Apparently this compound is not ionic in structure. The attached link refers to "cubic lattice containing two molecules of Mg3As2 in the unit cell."
A couple problems with this question: 1. There is no such compound as NaCl3. 2. Sodium is an alkali metal and Cl is a halogen, and the two would always form the ionic compound NaCl, not a covalent compound. You cannot draw Lewis structures for ionic compounds. You can draw Lewis electron diagrams for the individual ions (Na+ and Cl-), but not a structure for the ionic compound.
Metal (More specifically Ionic compound)
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.
crystal lattice
The metal's cubic lattice is made of only one kind of atom.

an ionic compound
Cobalt nitrate is an ionic compound.

Sodium isn't any kind of compound. It is an element.
Sodium hydroxide has ionic bonds. A compound never is any kind of bond.
It is an ionic compound - arranged in a giant lattice structure.
