The notation $\begin{array} { c } 
12 \
6
\end{array}$ C indicates that the carbon atom has an atomic weight of 12 and an atomic number of 6. The atomic weight is the sum of the number of protons and neutrons in the nucleus, so the carbon atom has 6 protons (since its atomic number is 6), and therefore 12-6=6 neutrons. The atom is electrically neutral, so it has the same number of electrons as it does protons, which is 6. Therefore, statement B is false, and the correct number of neutrons is 6, not 12.
