... If you are not given this symbol with the mass number, you can still determine the mass number for the most abundant isotopic form for that atom. For example, if you look on the periodic table for Carbon, you will see a value underneath its symbol - the RELATIVE ATOMIC MASS of 12.011. This mass is ...
