Answer:
Radioactive decay is defined as the disintegration of an unstable nucleus accompanied by the release of energy.
The different types of radioactive decay are: alpha decay, beta decay, gamma decay; which are accompanied by the release of photons or other subatomic particles.
The mass number (A) and charge number (Z) of the following products of radioactive decay are:
(a) a neutron : [tex]_{0}^{1}\textrm{n}[/tex]
A - 1
Z - 0
(b) an α- particle: [tex]_{2}^{4}\textrm{He}[/tex]
A - 4
Z - (+2)
(c) a positron : [tex]_{+1}^{0}\textrm{\beta }[/tex][tex]\beta[/tex]
A - 0
Z - (+1)
(d) a photon
A - 0
Z - 0
(e) a β- ray: [tex]_{-1}^{0}\textrm{\beta }[/tex][tex]\beta[/tex]
A - 0
Z - (-1)
