    Are you talking about the molar mass?

    Well... It's the small number under the letters of the element... What are they called?

    The small numbers underneath an element is the molar mass. It is the number of grams one mole of that substance contains. But, I have a suspicion you're looking at something else, since you're quoting a(n)...

    I'll give you an example. If this is correct, we're on the same page. Under carbon, you should see a number that's close to 12.011.

    If that's the kind of number you're thinking of, then that's the molar mass.

    Look at this periodic table - is 12.011 in the place you're thinking of (under carbon)?

    You might mean "atomic number" - it's the number of protons in the nucleus of the element. The atomic number defines what an element is. They're really the only two numbers that appear on a periodic table (molar mass and atomic number).
