A radioactive nucleus `._92 X^235` decays to `._91 Y^231`. Which of following particles are emitted ?

A

One alpha and one electron

B

Two deuterons and one positron

C

One alpha and one proton

D

One proton and four neutrons

Text Solution

Verified by Experts

The correct Answer is:
A
`""_(92)X^(235)overset(alpha)to_(90)X^(231)overset(beta^(-))to_(91)Y^(231)`
Therefore, one alpha and one electron are emitted.
