Which among these is /are correctly matched ?

A

Position emission : n/p ratio increase

B

K-electron capture : n/p decreases

C

`beta`- decay : n/p decreases

D

`""_(92) U^(238)` and `""_(90) Th^(231)` : n/p ratio decreases

Text Solution

Verified by Experts

The correct Answer is:
A, C
high `(n)/(p)` ratio `to {beta` - lim it} here `(n)/(p) darr_(s) ` , low `(n)/(p)` ratio `to` {K- `e^(-)` capture positron emits `alpha`- emit} here `(n)/(p) uarr`
