Sodium is considered a monoisotopic chemical element - sodium-23; the isotopes sodium-22 and sodium-24 exist only in ultrtraces.
Eleven. This because sodium has an atomic number (also the number of protons) of 11 on the periodic table. All the elements listed on the table are the most common (or only) isotopes of those elements.
It means that 1 mol of sodium (6.02x1023 sodium atoms) has a mass of 22.99 grams.It also means that 1 single sodium atom has a mass of 22.99 "amu", which is a very small unit of mass. You'll work with the first interpretation the most.
