An element `A` decays into element `C` by a two-step process :
`A rarr B + ._2 He^4`
`B rarr C + 2 e overline`
Then.

A

`A` and `C` are isotopes

B

`A` and `C` are isobars

C

`A` and `B` are is isobars

D

`A` and `B` are isobars

Text Solution

Verified by Experts

The correct Answer is:
A
`._(Z)A^(A)rarr._(Z-2)B^(A-4) +._(2)H_(e)^(4)`
`._(Z-2)B^(A-4)rarr._(Z)C^(A-4) +2_(-1)e^(0)`
