Question

In a radioactive decay, neither the atomic number nor the mass number changes. Which of the following particles is emitted in the decay?
(a) Proton
(b) Neutron
(c) Electron
(d) Photon

Answer 1

Electron
Is correct answer
Because
Atomic no. = no. Of proton
And
Mass no. = no. Of proton + no. Of neutron

Answer 2

Answer:

neutron

Explanation:

Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state. Gamma radiation is the most penetrating of all.

The neutron is a subatomic particle, symbol n or n 0 , with no net electric charge and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each .... A free neutron is unstable, decaying to a proton, electron and antineutrino ...
