Question

What happens to atomic masses in a chemical reaction where electrons are transferred or shared?

• A. Changes according to number of electrons being gained
• B. Does not change
• C. Remains the same in case of sharing, but it changes in case of losing or gaining electrons
• D. Increases

Answer 1

The correct option is D

Increases

The atomic mass does not change with chemical change. The loss or gain of electrons does not change the atomic mass because the mass of electrons is much lighter than nucleons. The mass of electrons is not considered for calculating the atomic mass.
