`""_(Z)X^(M)+""_(2)He^(4)to""_(15)P^(30)+""_(0)n^(1)`. Then

A

Z=12, M=27

B

Z=13, M=27

C

Z=12, M=17

D

Z=13, M=28

Text Solution

Verified by Experts

The correct Answer is:
B
`""_(Z)X^(M)+""_(2)H^(4)to""_(15)P^(30)+""_(0)n^(1)`
Z=15-2=13. M=31-4=27.
`""_(13)X^(27)+""_(2)He^(4)to""_(15)P^(30)+""_(0)n^(1)`.
