Question

What is the charge of Na2?

Answer 1

A charge on an element denotes the number of excess or deficient electrons present in the outermost shell of the element.

An element which has negative charge has the ability to denote electrons, and one which has positive charge has the ability to accept electrons. Each Na has a +1 charge.

Therefore for Na2, the net charge is +2.
