Question

Compare the properties of a metal and a non-metal on the basis of the following:

Electrochemical characters

Answer 1

Property	Metals	Non-metals
Electrochemical character	Metals are electropositive in nature, i.e. they lose electrons to form positively charged ions (cations). Examples $\mathrm{Na}-{\mathrm{e}}^{-}\to {\mathrm{Na}}^{+}$ $\mathrm{Mg}-2{\mathrm{e}}^{-}\to {\mathrm{Mg}}^{2+}$	Non-metals are electronegative in nature, i.e. they accept electrons to form negatively charged ions (anions). Examples $\mathrm{O}+2{\mathrm{e}}^{-}\to {\mathrm{O}}^{2-}$ $\mathrm{Cl}+{\mathrm{e}}^{-}\to {\mathrm{Cl}}^{-}$
