What happens to the mass number and the atomic number of an element when it emits gamma radiation?A. The mass number remains unchanged while the atomic number decreases by one.B. The mass number decreases by four and the atomic number decreases by two.C. The mass number increases by four and the atomic number increases by two.D. The mass number remnains unchanged while the atomic number increases by one.E. The mass number and atomic numbers remain unchanged.

The atomic number is the number of protons in the nucleus of an atom. An atom can be radioactive when the ratio of neutrons and protons is not optimal. It then decays emitting particles. A gamma ray is an electromagnetic wave. It is at the small wavelength end of the electromagnetic spectrum. A gamma ray has no mass and no charge. The general form of the equation for gamma decay is: Here, A is the mass number of a certain nuclide X Z is the atomic number (number of protons). As we see emitting a gamma ray makes no difference to the mass number or the atomic number of an element but will make the nucleus more stable. Hence, Option (E) is correct.
