The Attempt at a Solution

QUESTION: When you write an isotope, you would write the letter that stands for the elements, and then right next to that on the left you would write the mass number and the atomic number under neath the mass number ? Correct?

Yes, the atomic number would be in the subscript(bottom) to the left, and the atomic mass as the superscript(top). For example, carbon-13 would be written as ¹³₆C.
