Consider the following nuclear reaction for a `beta` decay `""_83X^210 to ""_84Y^210 + ""(-1)e^0`
In a `beta` m the neutron to proton ratio

Options

A. Increases
B. Decreases
C. Remains constant
D. May increase or decrease

Answer

B

Explanation

The given nuclear reaction is
`""_83X^210 to ""_84Y^210 + ""_(-1)e^0`
Before the reaction number of protons `(n_p) = 83`
and number of neutrons `(n_N) = 210 - 83 = 127`
`therefore (n_N)/(n_p) = 126/84 " but " 126/84 lt 127/83`
`therefore` Neutron to proton ratio decreases in `beta` decay .
