Question

From the list below, which item is not part of beta decay?

OA. The nucleus of the atom is unstable.
B. An atom has many more electrons than protons.
C. A neutron turns into a proton.
D. An electron is ejected from the nucleus

Answer 1

C

Step-by-step explanation:

When Beta decay happens, the atomic number of an element goes up, and that means there is an extra proton. A is not the answer because unstable atoms cause decay. B is also not correct because this is what happens in Beta decay: a neutron becomes a proton. D is not correct because an electron is actually emitted from the nucleus.

Answer 2

The correct answer is B. An atom has many fewer protons than neutrons.

I just took the test.
