WebThe underlying metal is a crystal, meaning its atoms have a certain ordered structure in space, with the atoms well bonded with each other. The native oxide, formed by reaction with oxygen or water in air, is amorphous, meaning its atoms are randomly distributed, and usually thin (4 nm or 0.000004 millimeters).

WebThe metals form cations, the nonmetals form anions, and the resulting compounds are solids under normal conditions. On the other hand, compounds formed between two or more nonmetals have small differences in electronegativity between the atoms, and covalent bonding—sharing of electrons—results.
