Question

The no.Of bond pairs and lone pairs of electrons in no3- ions are

Answer 1

Answer:

there are 3 bond pairs and 0 lone pairs in no3-

Explanation:

first calculate total number of valence electron of all atoms, therefore Nitrogen has 5 valence electrons and 3 oxygen atoms total 18 valence electrons.So total 24 electrons. divide by 8 we quotient as 3 so 3 bond pairs and remainder as 0 divide it by 2 we get 0 therefore 0 lone pairs
