The Lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group (red).In this representation, each Y atom needs electron(s) to complete its octet, and gains these electrons by forming bond(s) with atoms of H .There are unshared electron pair(s) and bonding electron pair(s) in the product molecule. The bonds in the product are (Ionic or Covalent)The element nitrogen would be expected to form covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the formula of the compound that would form between nitrogen and hydrogen , if the molecule contains only one nitrogen atom and only single bonds are formed. Formula:
