Which of the following nuclear reactions will generate an isotope ?

Options

A. Positron emission
B. `alpha`-particle emission
C. `beta`-particle emission
D. neutron particle emission.

Answer

D

Explanation

An isotope can be generated by the emission of positron, `alpha-` particle or `beta` particle because it will change atomic number of the parent nucleide. An isotope can be generated when the nuclei of an element are bombarded by slow neutron.
e.g. `""_(27)^(59)Co""+_(0)^(1)nto""_(27)^(60)Co`
(it is hypothetical process).
