Ne nucleus , the after absorbing energy , decays into two `a - particle` and an unknown nucleus . The unknown nucleus is

A

nitrogen

B

carbon

C

boron

D

oxygen

Text Solution

Verified by Experts

The correct Answer is:
B
`_(10)^(22)Ne rarr _(2)^(4)He + _(2)^(4)He + _(6)^(14) X `
The new element `X` has atomic number `6` . Therefore , it is carbon atom .
