Assetion In alpha-decay atomic number of...

Assetion In `alpha`-decay atomic number of daughter nucleus reduces by 2 units from the parent nucleus.
Reason An `alpha` particle carries four units of mass.

A

Both assertin and reason are true and reason is the correct explanation of assertion

B

Both assertion and reason are true but reason is not the correct explanation of assertion

C

Assertion is true but reason is flase

D

Both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
We know that `alpha` particle carries two units of positve charge and four units of mass In `alpha` decays charge number of parent nucleus decreses by 2 units Alos mass number reduces by four units.
