You are given a n element `overset(16)underset(8)X`. Find out
(a) Number of protons electrons and neutrons in X.
(b) Valency of 'X'.
Write the chemical formula of the compound formed when 'X' reacts with(i) hydrogen,(ii) carbon.

Explanation

(a) Number of protons =8
Number of electrons=8
Numbr of neutrons=16-8=8
Electronic configuration =2,6
(b) Valency of 'X' = 8-6=2
(c ) The element 'X' is 'O' The formula of the compunds with hydrogen (H) and oxygen (O) are :
(i) `H_(2)O(ii) CO_(2)`
