A radioactive element forms its own isotope after 3 consecutive disintegrations. The particles emitted are
A
-particles
B
-particles and 
-particle
C
-particles and 
-particle
D
-particles and 
-particle.
Text Solution
Verified by ExpertsThe correct answer is:
B
A nucleus is denoted by 
An isotope should have same 
.
-particle 
-particle 
The emission of one 
particle and the emission of two 
particles maintain the 
same.
Hence for isotope formation 
particles and one 
particle are emitted.
