Question

Which of the following nuclear reactions will generate an isotope ?

• A. Neutron particle emission
• B. Positron emission
• C. $\alpha$ -particle emission
• D. $\beta$ -particle emission

Answer 1

Answer: (A)

Neutron particle emission

Answer 2

The atoms of the some elements having same atomic number but different mass numbers are called isotopes.

(1)${}_{Z}^{A}X{\overset{\quad - \alpha\quad}{\rightarrow}}_{Z - 2}^{A - 4}Y$ Y(2)${}_{Z}^{A}X{\overset{\quad - \beta\quad}{\rightarrow}}_{Z + 1}^{A}Y$

(3)${}_{Z}^{A}X{\overset{\quad -_{0}^{1}n\quad}{\rightarrow}}_{Z}^{A - 1}Y$ X (4)${}_{Z}^{A}X{\overset{\quad - \beta + \quad}{\rightarrow}}_{Z - 1}^{A}Y$
