The atomic number of an element X is 16.(a) Write down the electronic configuration of X.(b) What will be the valency of X ?

Academic Chemistry NCERT Class 9

Atomic No. of X = 16

(a) The electronic configuration of X is

K L M

2 8 6

(b) The outermost orbit has 6 electrons. In order to make it 8, X will have to gain 2 electrons. So, the valency of X is 2.
