Question

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

Answer 1

Unknown. Likely, both isotopes are neutral.

Explanation:

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.
