Problem

POLAR OR NON-POLAR? WHY? 

(a) Phosphate, PO43- 

(b) Potassium lon 

(c) Nitrous oxide 

(d) Magnesium ion 

(e) Nitrogen, N2

Solution

We are being asked if the given compounds are either polar or non-polar. This can be done by following the steps below: 

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Draw dipole arrows for each bond.

Step 5: Determine the polarity of the molecule.
