Which group of nuclear emissions is listed in order of increasing charge?
(1) alpha particle, beta particle, gamma radiation
(2) gamma radiation, alpha particle, beta particle
(3) positron, alpha particle, neutron
(4) neutron, positron, alpha particle

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 or .

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 .

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 . 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.
