Use the equation to answer the prompt.

Question

106
C→ 105
B + 0+1
e

The student is incorrect because in beta-minus decay, the atomic number of the nucleus increases by one

Answer 1

, not decreases. This can be seen in the equation provided, where the atomic number of the initial nucleus (106) is greater than the sum of the atomic numbers of the resulting nucleus (105) and the emitted beta particle (+1).

Answer 2

out of these choices which is the answer

Answer 3

The student is incorrect because in beta-minus decay, the atomic number of the nucleus increases by one.
