Consider the following nuclear reaction :
`""_(92)^(238)Mto""_(y)^(x)N+2""_(2)^(4)He`
`""_(y)^(x)Nto""_(B)^(A)L+2beta^(+)`
The number of neutrons in the element L is

A

140

B

144

C

142

D

146

Text Solution

Verified by Experts

The correct Answer is:
B
`""_(92)^(234)Mto""_(88)^(230)N+2""_(2)^(4)He`
`""_(88)^(230)Nto_(86)^(230)L+2""_(+1)overset(0)e`
No. of neutrons =230-86=144
