cfa - atoms, periodic table,and ions\nidentify the number of neutrons in the element carbon - 14\no 6\no…

Explanation:

Step1: Recall atomic number of carbon

The atomic number of carbon ($C$) is 6, which means the number of protons is 6.

Step2: Use mass - number formula

The mass - number ($A$) of an atom is the sum of the number of protons ($p$) and neutrons ($n$), i.e., $A=p + n$. For carbon - 14, $A = 14$ and $p=6$.

Step3: Calculate number of neutrons

We can re - arrange the formula $A=p + n$ to $n=A - p$. Substituting $A = 14$ and $p = 6$ into the formula, we get $n=14 - 6=8$.

C. 8
