Which of the following nuclear reactions will generate an isotope?
A.
$$\beta $$ - particle emission
B.
Neutron praticle emission
C.
Positron emission
D.
$$\alpha $$ - particle emission.
Answer :
Neutron praticle emission
Solution :
NOTE : Isotopes are atoms of same element having same atomic number but different atomic masses. Neutron has atomic number 0 and atomic mass 1. So loss of neutron will generate isotope. e.g.,
$$_{92}{U^{238}}{ + _0}{n^1}{ \to _{92}}{U^{239}}$$
