Question

Q7: When a neutron leaves the
nucleus, it's mass
a. Triples
b. Decreases
C. Increases
d. Stays the same​

Answer 1

Answer:

When a neutron leaves the nucleus its mass (Decreases)

Answer 2

When a neutron leaves the nucleus, its mass decreases. (option b).

What is a neutron?

• A neutron is a neutral particle found in the nucleus of an atom. Along with protons, neutrons make up the nucleons.
• The mass of a neutron is 1.674920 × $10^{-24}$ gram; almost equal to that of a proton.

What happens when a neutron leaves the nucleus?

• When a neutron leaves the nucleus, its atomic number decreases.
• A decrease in the atomic number denotes a decrease in the mass of the nucleus, as the relative mass of a neutron is 1.
• Thus, for example, a deuterium atom (H²) has 1 more neutron than a Hydrogen(H¹) atom, so the mass of deuterium is more than that of hydrogen.

Hence, when a neutron leaves the nucleus, its mass decreases.

Option b is correct.
