# "Isotopes A" and "B" EACH have six protons. A has six neutrons, and B has eight neutrons. What are the charges of each isotope?

Isotope $A$ has 12 nuclear particles. Since there are 6 protons, the element $A$ is ""^12C, and $B$ is ""^14C. I can define the identity of the element and its mass, simply by atomic number and number of neutrons. Since carbon rarely forms ions, I guess there are 6 electrons associated with each isotope, giving neutral atoms, but the number of electrons was unspecified.
