Which of the following will emit positron?

`._(15)^(30)P`

`._(7)^(13)N`

`._(1)^(3)H`

`._(6)^(14)C`

Text Solution

Verified by Experts

The correct Answer is:

a,b

`._(15)^(30)P ((n)/(p) = 1)` and `._(7)^(13)N ((n)/(p) lt 1)`: these nuclei emit positrons.
`._(15)^(30)P to ._(14)^(30)Si + ._(+1)^(0)e`
`._(7)^(13)N to ._(6)^(13)C + ._(+1)^(0)e`
