Sagot :
The nuclear emissions is listed in older of increasing charge are: Neutrons, positron, alpha particles.
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 [tex]^{4}_{2}\alpha[/tex] or [tex]^{4}_{2}He[/tex].
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 [tex]^{0}_{+1}\beta[/tex].
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 [tex]^{0}_{0}\gamma[/tex]. 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.
