# Do metals tend to form positive or negative ions?

May 8, 2017

A metal tends to be reducing.........

#### Explanation:

And thus metals tend to form positive ions.

$M + \Delta \rightarrow {M}^{2 +} + 2 {e}^{-}$

At an atomic level, the valence electrons of the metal are conceived to be delocalized across the close-packed array of metal atoms (metal ions), i.e. $\text{positive ions in an electron sea}$. And this gives rise to the phenomenon of metallic bonding, which entails (i) malleabililty; (ii) ductility; and (iii) conductivity to heat and electricity.
