Question

Which group of nuclear emissions is listed in order of increasing charge?

Answer 1

Answer: Option (4) is the correct answer.

Explanation:

An alpha particle is basically a helium nucleus and it contains 2 protons and 2 neutrons. Symbol of an alpha particle is $^{4}_{2}\alpha$ or $^{4}_{2}He$.

This means that an alpha particle carries a +2 charge.

A positron is a small particle which contains a +1 charge. And, a positron is represent by the symbol $^{0}_{+1}\beta$.

A neutron is a sub-atomic particle present inside the nucleus of an atom. Charge on a neutron is 0.

A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.

Symbol of a gamma particle is $^{0}_{0}\gamma$. Hence, charge on a gamma particle is also 0.

Therefore, we can conclude that group of nuclear emissions from neutron, positron, alpha particle is listed in order of increasing charge.

Answer 2

The nuclear emissions is listed in older of increasing charge are: Neutrons, positron, alpha particles.
