Solution
The correct option is A 0
Electrons are negatively charged while protons are positively charged sub-atomic particles.
A sodium atom has 11 electrons and 11 protons. The total positive charge of the protons is balanced by the total negative charge of the electrons.
As a result, sodium atom is neutral i.e., the total electrical charge on it is zero.
0
