Nucleus A is converted into C through the following reactions, `ArarrB+alpha`
`BrarrC+2 beta`
then,

A

(a) A and B are isotopes

B

(b) A and C are isobars

C

(c) A and B are isobars

D

(d) A and C are isotopes

Text Solution

Verified by Experts

The correct Answer is:
D
By emitting one `alpha`-particle, atomic number decreases by 2. By emitting two `beta`-particles, atomic number increases by 2. Hence,
`Z_A=Z_C`
or A and C are isotopes.
