Question

What is the change in atomic number when an atom emits a beta particle?

Answer 1

When an atom emits a beta

particle from the nucleus, the nucleus only has one more proton and one less

neutron and this will make the atomic mass number remains unchanged while the

atomic number increases by 1.

Answer 2
