(a)
Interpretation:
The balanced equation for the decay reaction of the given isotope is to be stated.
Concept introduction:
The type of radioactive decay in which an alpha particle is emitted by the nucleus of an atom such that an atom of another element is produced after decay is known as alpha decay. An alpha particle is a helium nucleus. The radioactive decay in which a positron or an electron is emitted is known as beta decay.

Answer to Problem 10.12E
The balanced equation for the decay reaction of the given isotope is,
Explanation of Solution
The given parent nucleus is
The net mass is obtained by subtracting the mass of the emitted particle from the mass of the parent nucleus. Therefore, the net mass is,
The net charge is obtained by subtracting the charge on the emitted particle from the charge on the parent nucleus. Therefore, the net charge is,
