Question

a nucleus decays to produce a nucleus with one additional proton. which type of decay did the nucleus undergo? (1 point)

beta - minus decay
gamma decay
beta - plus decay
alpha decay

Explanation:

Beta - minus decay occurs when a neutron in the nucleus changes into a proton, an electron, and an antineutrino. This results in an increase of one proton in the nucleus. Gamma decay only involves the emission of gamma - rays and does not change the number of protons or neutrons. Beta - plus decay reduces the number of protons. Alpha decay emits an alpha particle (2 protons and 2 neutrons), reducing the number of protons.

Answer:

beta - minus decay
