Decrease in atomic number is observed during :

A

Alpha emission

B

Beta emission

C

Positron emission

D

Electron emission

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`alpha` emission : `._(Z)X^(A)rarr ._(Z-2)Y^(A-4)+ ._(2)He^(4)`
Positron emission : `._(Z)X^(A)rarr ._(Z-1)Y^(A)+ ._(+)e^(0)+V`
Electron capture : ` ._(1)p^(1)+ ._(-1)e^(0) rarr ._(0)n^(1)+V`
