Metal je loše definiran pojam, točnije podjela na metale i nemetale nije, strogo govoreći, znanstvena (kemijska) nego tradicionalna. U radu se razmatraju opća svojstva elemenata nastojeći pronaći kriterije za određivanje njihove kako metalne tako i nemetalne naravi. “Metalni” spojevi nemetala i “metalni” spojevi nemetala te dublje razumijevanje pojma elektronegativnosti ukazuju međutim na činjenicu kako metalna narav elementa nije apsolutna, nego relativna, ovisna o elementu s kojim ulazi u kemijsku vezu.

Closer analysis reveals, however, that there are no universal properties of metals, and that virtually every chemical element could be regarded as metal as well as nonmetal. The metalic character of an element depends on its chemical combination. This is visible from the comparison of “metallic” compounds of nonmetals and “nonmetallic” compounds of metals, as well as from the nature of the chemical bond (covalent/ionic), as deduced from the difference in electronegativity of the constituting atoms.
