Bohr was able to reproduce the Periodic Table, adding one electron at a time as one stepped to the next higher element. Bohr argued that orbits of increasing radius could accommodate up to a maximum number of electron numbers that, when reached, corresponded to observed horizontal periods of tw...
No matter whether "formula mass" or "relative formula mass" is calculated all of the method steps and wer are the same.唔系应该 formula mass = mass number + mass number +... relative formula mass = relative atomic mass + relative atomic mass+...(periodic table个数字) 咩?

Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus. All isotopes of an element fall under a single cell on the periodic table, since they all share the same atomic number. ...
Every nucleus of a given chemical element has the same number of protons, and this quantity of protons defines the atomic number of the element and determines the element’s position in the periodic table. The discovery of the proton dates to the earliest investigations of atomic structure. ...
