What statement is not true when two neutrons are added to oxygen-16.?
.

a) the oxygen atom becomes an isotope

b) the charge of the oxygen atom changes

c) the mass of the oxygen atom increases

d) the mass of the oxygen nucleus increases

 B) the charge of the oxygen atom changes

Explanation: Neutron is a subatomic particle which is neutral and bears no charge but has significant mass.

Isotopes are elements which have same atomic number but different mass number.

As the neutrons are added, the mass number of the element changes and thus an isotope of oxygen will be formed.

The charge will not change as the neutrons are neutral in nature.
