#"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.

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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
