Question

Write the identity of the missing nucleus for the following nuclear decay reaction:

?→59Co+0e

27 -1

Express your answer as an isotope.

Answer 1

Given reaction is $B-negative$ decay

The complete reaction is given by-

$_{26}Fe^{59}\rightarrow _{27}\text{Co}^{59}+_{-1}e^{0}$

Hence The missing species is Iron  $_{26}Fe^{59}$ .
