Most metals are reliable at place temperature, but this does not should be the case. Mercury is liquid. Alloys are mixtures, in which a minimum of one part of the combination is usually a metal.
delocalized electrons: Electrons of an atom, molecule or metal that are not associated with a particular atom or a particular covalent bond. As a substitute, they roam freely. Delocalized electrons are characteristic of metallic bonds and sometimes are referred to as a sea of electrons.
