What do metals do with their valence electrons when they form chemical bonds?

Answer 1

Metals generally transfer their electrons, in other words are oxidised to form cations, such as Na+ and Fe3+

In a metallic bond the valence electrons are delocalised around the lattice (in the solid) or the metal atoms in molten state (sea of electrons model)

Metal atoms can also form covalent bonds, these are most common amongst the more electronegative metals, in these, as in any other covalent bond the electrons are shared (generally in a polar covalent bond)

Answer 2

Metals typically lose their valence electrons when forming chemical bonds, becoming positively charged cations. Losing electrons allows metals to achieve a stable electron configuration and form bonds with other elements, usually nonmetals, to create ionic compounds.

Answer 3

the valence electrons of atoms in a pure metal can be modeled as a sea of electrons.

Answer 4

valence electrons in a metal is being transferred
