We are asked what is the daughter nucleus produced when 103(Mo) undergoes beta deca
Recall that in a nuclear reaction, the number of protons and neutrons are affected and the identity of the element changes. For Beta decay: forms a beta particle (0–1β, atomic mass = 0, atomic number = –1). The beta particle appears in the product side.
The incomplete nuclear equation is:
10342 Mo → ___ + 0–1β,
Atomic mass of the daughter nuclide:
103 = x + 0
x = 103 – 0 = 103
What is the daughter nucleus produced when 103(Mo) undergoes beta decay?
