valency is combining capacity of an atom.Electric configuration of magnesium is
1s²2s²2p^63s²
in outermost shell there r two electron to be losed to attain noble gas configuration or it can gain 6 electron to attain noble gas configuration . but losing is much easy than gaining so VALENCY OF MAGNESIUM IS 2
