Calculate the number of betaparticles , ...

Calculate the number of `beta`particles , If a radioactive element `_(90)X^(238)` dacays into `_(83)gamma^(222)`.

A

4

B

6

C

2

D

1

Text Solution

Verified by Experts

The correct Answer is:
D
Number of `alpha`- particles emitted = `(238 - 222) / 4 = 4`
and `beta`- particle = 1 (as atomic number is 83)
