Homework Help: When an isotope is written out vs. writing out something on table of element chart

  1. Feb 5, 2010 #1
    1. The problem statement, all variables and given/known data


    Like, if you are writing out one of the blocks on the table of elements chart, you would write out the letter of the element, and then you would write the atomic average (or atamoic mass it is also known as,) on the bottom left , and the atmomic mass on the top to the right (thats how it usually is)


    2. Relevant equations



    3. 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.
