Question

in a beta decay:
the parent and daughter nuclei have the same number of protons
none of the above
the daughter nucleus has one proton more than the parent nucleus
the daughter nucleus has one proton less than the parent nucleus
iron - 56 undergoes gamma decay to produce what daughter isotope and decay particle?

Explanation:

In beta - decay, a neutron in the parent nucleus is converted into a proton, an electron, and an antineutrino. So the daughter nucleus has one more proton than the parent nucleus. In gamma decay, the nucleus transitions from a higher - energy state to a lower - energy state without changing the number of protons or neutrons, so the daughter isotope is still iron - 56 and the decay particle is a gamma ray.

Answer:

For the beta - decay question: The daughter nucleus has one proton more than the parent nucleus
For the iron - 56 gamma - decay question: The daughter isotope is iron - 56 and the decay particle is a gamma ray.
