Chlorine atom (Cl) has elctronic configuration of 2,8,7 .
Its valency is 1- (The atomic number of Chlorine is 17.Since Chlorine has 7 electrons in its valence shell it would take much less energy to acquire an electron an reach the stable 8 electrons in a shell configuration rather than loosing its 7 electrons. Hence the valency of Chlorine is 1.)
hope it helps you:-)
