AIPMT MAINS 2009 Physics Radioactivity MCQ Question
Type: MCQ-conceptual-Medium-Class 12
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
Correct Answer
Option C
Detailed Explanation
Emission of beta particles increases the atomic number by 1, while alpha emission decreases it by 2. If beta particles are twice the alpha particles, the net change in atomic number is zero, resulting in an isotope.
