Isotopes. The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also known as atomic weight (symbol: A r ). m: Tellurium (Te) has an atomic mass of 52.

1 Answer. Their atomic masses are the 'wrong way round'. If you look at Iodine and Tellurium on the modern periodic table, you will find their atomic number increases (Te is 52, I is 53) but their atomic mass decreases (Te is 128, I is 127). Mendeleev only had access to the atomic masses at the time he was developing the …
