122 · A list of current, dated, as well as proposed and historical signs and symbols is included here with its signification.Also given is each element's atomic number, atomic weight or the atomic mass of the most stable isotope, group and period numbers on the periodic table, and etymology of the symbol.. Hazard pictographs are another type of symbols used in chemistry.
The mass of an element that is numerically equal to the atomic mass A in grams is called a mole and will contain Avogadro's number N A of nuclei. If the density ρ of the material is known, then the number of nuclei per unit volume n can be calculated from n =ρN A /A. This is useful in calculating the cross section for nuclear scattering.
Most chemical elements are represented symbolically by two letters, generally the first two in their name. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. A very few elements have symbols which appear to have no relationship with their names.
