Which of the following is true concerning gamma radiation?
A. The mass number of the radioisotope decreases by four.
B. The atomic number of the radioisotope decreases by two.
C. The atomic number of the radioisotope increases by one.
D. Neither the mass number nor the atomic number changes****
right
To determine which of the options is true concerning gamma radiation, we need to understand the characteristics of gamma radiation.
Gamma radiation is a type of electromagnetic radiation that is highly energetic and is emitted from the nucleus of an atom during radioactive decay. Unlike alpha and beta particles, gamma rays do not carry any charge or mass. Therefore, gamma radiation does not result in any changes to the mass number or the atomic number of the radioisotope.
Option D "Neither the mass number nor the atomic number changes" is the correct choice.
