Find the number of neutrons in a parent ...

Find the number of neutrons in a parent nucleus `X`, which gaves `._(7)N^(14)` after two succe3ssive `beta-` emission.

Text Solution

Verified by Experts

The correct Answer is:
`9`
`._(5)X^(14) rarr ._(7)N^(14) + 2 ._(+1)e^(0)`
`:.` Number of neutrons `= 14 - 5 = 9`
