WebThere were seven elements (with Z < 92) which were not found and therefore identified as still undiscovered, corresponding to atomic numbers 43, 61, 72, 75, 85, 87 and 91. [5] From 1918 to 1947, all seven of these missing elements were discovered. [6] WebThe nucleus is composed of protons and neutrons. 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 …

In chemistry an element is a species of atom having the same number of protons in its atomic nuclei (that is, the same atomic number, or Z ). [1] For example, the atomic number of oxygen is 8, so the element oxygen describes all atoms which have 8 protons. In total, 118 elements have been identified.
