Question

Metals are good because they are electron .

Answer 1

• Metals are low ionization energy and electropositive in nature because they have the tendency to lose electrons easily.

$\mathrm{Na}\left(\mathrm{s}\right)-1{\mathrm{e}}^{-}\to {\mathrm{Na}}^{+}\left(\mathrm{ion}\right)$

• They donate electrons and get oxidized. For example, magnesium on a reaction with oxygen forms magnesium oxide by donating the electrons to oxygen.

$2\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right)$

Hence, Metals are good reducing agents because they are electron donors.
