Science - physics: What happens to the atomic number and mass number during alpha, beta and gamma decay?

Question

What happens to the atomic number and mass number during alpha, beta and gamma decay?

Alana Ray · Accepted Answer

During alpha decay, the atomic number decreases by 2 and the mad number decreases by 4

While in beta decay, the atomic number decreases by 1, but the mass number does not change

And in gamma decay the atomic and mass number do not change at all
