`.^22 Ne` nucleus after absorbing energy decays into two `alpha-`particles and an unknown nucleus. The unknown nucleus is.

nitrogen

carbon

boron

oxygen

Text Solution

Verified by Experts

The correct Answer is:

Atomic number of neon is `10`
By the emission of two `alpha`-particles, atomic number will be reduced by `4`. Therefore, atomic number of the unknown element will be `Z=10-4=6`
Similarly mass number of the unknown element will be `A=22-2xx4=14`
`:.` Unknown nucleus is carbon `(A=14, Z=6)`
