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
`._(Z)Z^(A) overset(-alpha)rarr ._(z-2)Y^(A-4) (alpha- "emission" )`
`underset(beta-"emission")(._(Z)^(A)+) ._(-1)e^(0)rarr._(z-1)Y^(A)`
`._(Z)X^(A-)overset(._(+)e^(0))rarr._(z-1)Y^(A-4) ("positron - emission ")`
`._(Z)A^(A)+._(-1)e^(0) rarr ._(Z-1)Y^(A) ("electron capture ")`
