Question

How many chemical bonds are in KNO3? What are their names?

Answer 1

Well, there is the ionic bond between `K^+` and `NO_3^(-)` ions......

Explanation:

And also there is the covalent bond that operates in the nitrate anion..... The usual Lewis structure depicts a quaternized nitrogen (i.e. a nitrogen with a formal positive charge), a doubly bound `N=O` bond, and `2xxN-O^-` singly covalent bond....

i.e. `O=stackrel+N(-O^(-))_2`

Of course all the `N-O` bonds are equivalent, with the negative charges delocalized over 4 centres.....
