The isotopes of an element differ in the number or neutrons whereas the number of protons or electrons of a neutral atom stays the same. The molar mass of the element is based on the percent abundances of different isotopes and the individual molar mass of each isotope.
a...if you had the fully extended periodic table, these elements would be between La and Hf in period 6 and Ac and Rf in period 7
