What kind of chemical bond is typical for metals?

Metals, unlike non-metals, have certain similar properties:

metallic luster, high malleability, good electrical and thermal conductivity. These properties are determined by the metallic bond. Metal atoms on the outer layer have a small number of electrons, Li has one, Al has three. Therefore, metal atoms easily donate external electrons, turning into a positive ion, in contrast to non-metals. Having torn off, the electrons move from one ion to another, connecting with another ion, temporarily form an atom again. That is, there is a constant tearing off of electrons from atoms and their attachment to ions. This can be written by the equation:

Me0 − ne– ⇄ Men +,

where Me0 is a metal atom, n is a number, e is an electron, n is the number of electrons, Men + is the number of metal ions. The arrows show that the reaction goes both from left to right and from right to left.

A metallic bond is a bond between positive ions and metal atoms through shared electrons.

It is free electrons that give metals their physical properties.

The metallic bond is characteristic only for solid and liquid metals. In the vapor state, a covalent bond occurs in metals.
