Vedclass · Answer

(C) The atomic number $Z$ represents the number of protons and electrons in a neutral atom. For both $^{12}C$ and $^{14}C$,$Z = 6$,so both have $6$ protons and $6$ electrons.The mass number $A$ is the sum of protons and neutrons $(A = Z + N)$.For $^{12}C$: $A = 12$,so $N = 12 - 6 = 6$ neutrons.For $^{14}C$: $A = 14$,so $N = 14 - 6 = 8$ neutrons.Comparing the two,$^{14}C$ has $8 - 6 = 2$ extra neutrons and the same number of protons and electrons. Thus,option $C$ is correct.

As compared to a $^{12}C$ atom,a $^{14}C$ atom has:
