For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting nucleus will now change (as compared to your starting nucleus) by O A. zero O B. minus 1 ) C. minus 2 D. minus 3

Expert Solution
Step 1
First, we define alpha decay, beta plus decay, beta minus decay, and gamma decay.
Alpha decay: In alpha decay, the parent isotope emits two protons and two neutrons.
Atomic number decreases by two.
Beta plus decay: Proton converts to a neutron, positron, and neutrino.
Atomic number decreases by one.
Beta minus decay: Neutron converts to a proton, electron, and antineutrino.
Atomic number increases by one.
Gamma decay: In gamma decay, some unstable nuclei dissipate excess energy by a spontaneous electromagnetic process. Photons or energy packets are radiated.
No change in atomic number.
