Beryllium (4 Be) has 12 known isotopes, but only one of these isotopes (9 Be) is stable and a primordial nuclide.As such, beryllium is considered a monoisotopic element.It is also a mononuclidic element, because its other isotopes have such short half-lives that none are primordial and their abundance is very low (standard atomic weight is 9.0122). Garden Pizza. Convert grams beryllium to moles or moles beryllium to grams ... of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. This signifies that boron-10 contains five protons. Bromine is a chemical element with atomic number 35 which means there are 35 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. 4.0 mol. Mole-Mass and Mole-Volume Relationships. The atomic number of beryllium (Be) is 4, and the atomic number of barium (Ba) is 56.
