Elements are represented by their chemical symbols sometimes with atomic and mass numbers, as shown below. The mass number is the sum of the number of neutrons and protons in the nucleus. Scientists have standardized a simple way to represent elements with their chemical symbols.

One of the main reasons for development is that using letters is the easiest way to represent elements. Another reason to use chemical symbols is that they make it easier to write chemical formulas. The periodic table is a tabular arrangement of the chemical elements from hydrogen which has the lowest atomic number to oganesson which has the highest atomic number. The atomic number of an element is the number of protons in the nucleus of that element.
