Gaining neutrons makes an element?

A more positive in electrical charge

B more negative in electrical charge

C have no change in electrical charge

C. Have no change in electrical charge

Explanation:

If a element gains neutron it become an Isotope. The electrical charge do not change for this, only the atomic mass changes when an element gains neutrons.

The electrical charge is affected when there is a variation in the number of electrons or protons in the element.
