WebCharacteristic properties of non-metals are high ionization energies and high electronegativity. Owing to these properties, non-metals usually gain electrons when react with other compounds, forming covalent bonds. The following are the general properties of non-metals. The atoms of non-metals tend to be smaller than those of metals.
