When a parent radioactive nucleus splits by ejecting an alpha particles (two protons and two netutrons), the

remaining nucleus has ____ the original nucleus.

a) two protons and two neutrons more than
b) two protons more and two neutrons less than
c) two protons less and two neutrons more than
d) two protons and two neutrons less than
e) the same number of protons and neutrons as

Eject means getting rid of something Does that help you?

I apologize for the mistake. Here is the corrected answer:

When a parent radioactive nucleus splits by ejecting an alpha particle (two protons and two neutrons), the remaining nucleus has two protons and two neutrons less than the original nucleus. Therefore, the answer is (d).

To determine the answer, we need to understand the process of alpha decay. In alpha decay, a parent radioactive nucleus splits by ejecting an alpha particle, which consists of two protons and two neutrons.

Let's analyze the options:

a) two protons and two neutrons more than: This is incorrect because the alpha particle consists of two protons and two neutrons. The remaining nucleus would have two protons and two neutrons fewer, not more.

b) two protons more and two neutrons less than: This is also incorrect because the alpha particle consists of two protons and two neutrons. Therefore, the remaining nucleus would have two protons and two neutrons fewer, not more.

c) two protons less and two neutrons more than: This is the correct option. The parent nucleus ejects an alpha particle, which contains two protons and two neutrons. As a result, the remaining nucleus would have two protons less and two neutrons more compared to the original nucleus.

d) two protons and two neutrons less than: This is incorrect because the alpha particle contains two protons and two neutrons. Thus, the remaining nucleus would have two protons and two neutrons fewer, not the same.

e) the same number of protons and neutrons as: This is incorrect because the alpha particle carries away two protons and two neutrons. Therefore, the remaining nucleus would have a different number of protons and neutrons than the original nucleus.

Based on the explanation, the correct answer is option c) two protons less and two neutrons more than the original nucleus.
