How does a metal react with a nonmetal ?

Answer»

Solution :By oxidation of a metal, cations are formed, on the other handby REDUCTION of a nonmetal, anions are formed. The ionic compound is formed due to the metal losing electronswhile the nonmetal acceptsthe electrons . The ionic compound of SODIUM chloride is formed as sodium loses one electron while chlorine ACCEPTS one electron .
`Na to Na^(+) + e^(-)`
` CI+ e^(-) to CI^(-)`
`overline (Na+Ci to NACI)` Sodium chloride
Similarly Mg and K form ioniccompounds `MgCI_(2) adn KCI`
