Explanation:
By knowing the structure of the compound you can easily identify the bond pair and lone pairs in a compound.
* For example in NH3 there are three H attached to the central atom N and there is an extra pair of electrons which have not taken part in bonding, which is the lone pair.
* Again in H2O there are 2 H atoms attached to oxygen so there are 4 electrons left which forms two lone pairs.
*Moreover you can see it this way Lone Pair= (no of valance shell electrons of the central atom - no of electrons taken part in bonding)/2.
