Question 6

Which equation represents the β\betaβ-decay of cobalt-60?

A

2760Co+  −10e→  2860Ni^{60}_{27}\text{Co} + \;^{0}_{-1}\text{e} \rightarrow \;^{60}_{28}\text{Ni}2760​Co+−10​e→2860​Ni

B

2760Co+  −10e→  2660Fe^{60}_{27}\text{Co} + \;^{0}_{-1}\text{e} \rightarrow \;^{60}_{26}\text{Fe}2760​Co+−10​e→2660​Fe

C

2760Co→  2860Ni+  −10e^{60}_{27}\text{Co} \rightarrow \;^{60}_{28}\text{Ni} + \;^{0}_{-1}\text{e}2760​Co→2860​Ni+−10​e

D

2760Co→  2660Fe+  −10e^{60}_{27}\text{Co} \rightarrow \;^{60}_{26}\text{Fe} + \;^{0}_{-1}\text{e}2760​Co→2660​Fe+−10​e
