The type of radioactivity that removes excess energy from the nucleus without changing the atomic number or mass number is called:

Question

Quizplus · Accepted Answer

Gamma decay involves emission of high-energy photons from the nucleus. It does not change the atomic number or mass number of the nucleus. Alpha decay involves emission of alpha particles (helium nuclei) and decreases the atomic number by 2 and mass number by 4. Beta decay involves emission of beta particles (electrons or positrons) and changes the atomic number by 1 but does not affect the mass number. Electron capture involves capturing an electron from the atom and decreasing the atomic number by 1, but again, it does not affect the mass number.
