What are the correct mass and charge numbers for the following five products of radioactive decay: (a) a neutron (b) an α- particle (c) a positron (d) a photon (e) a β- ray

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 :

A - 1

Z - 0

(b) an α- particle:

A - 4

Z - (+2)

(c) a positron :

A - 0

Z - (+1)

(d) a photon

A - 0

Z - 0

(e) a β- ray:

A - 0

Z - (-1)

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
