If `._(92)U^(235)` assumed to decay only by emitting two `alpha`-and one `beta`-particles, the possible product of decays is a)`._(89)Ac^(231)` b)`._(89)Ac^(235)` c)`._(89)Ac^(236)` d)`._(89)Ac^(227)`

A

`""_(98)AC^(211)`

B

`""_(89)Ac^(235)`

C

`""_(89)Ac^(235)`

D

`""_(89)Ac^(227)`

Text Solution

Verified by Experts

The correct Answer is:
D
`""_(92)U^(235) underset(-beta)overset(-2alpha)rarr ""_(89)Ac^(227)`
Loss of `alpha` particles decreases at no. by 2 and mass no. by 4, whereas emission of `+ beta`- particles increases at. No .by 1.
