""(Z)X^(M) +""(2)He^(4) rarr ""(15)P^(30...

`""_(Z)X^(M) +""_(2)He^(4) rarr ""_(15)P^(30)+""_(0)n^(1)` value of X is

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)He^4 to ""_(15)P^(30) + ""_(0)n^1`
Z+2 = 15 + 0
Z= 13
M + 4 = 30 + 1
M= 27
