Question 25
H

A nucleus of carbon-13 emits a neutron. The nuclear equation is 613C→baC+01n^{13}_{6}\text{C} \rightarrow {}^{a}_{b}\mathrm{C} + {}^{1}_{0}\text{n}613​C→ba​C+01​n. What are the values of a a\,a and bbb?

[1]
A

a=12a = 12a=12 and b=5b = 5b=5

B

a=13a = 13a=13 and b=5b = 5b=5

C

a=12a = 12a=12 and b=6b = 6b=6

D

a=13a = 13a=13 and b=6b = 6b=6
