Question

The number of beta particles emitted by a radioactive substance is twice the number of alpha particles emitted by it. The resulting daughter is an

• A. Isomer of parent
• B. Isotone of parent
• C. Isotope of parent
• D. Isobar of parent

Answer 1

Answer: (C)

Isotope of parent

Answer 2

: ${}_{Z}^{A}X{\overset{\quad 2\beta^{-}\quad}{\rightarrow}}_{Z + 2}^{A}Y_{1}{\overset{\quad\alpha\quad}{\rightarrow}}_{Z}^{A - 4}Y_{2}$

The resultant daughter is an isotope of the original parent nucleus.
