Atomic number The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of its atomic nucleus For ordinary nuclei composed of protons and neutrons, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element

relative atomic mass (also called atomic weight; symbol: Ar), which is the ratio of the average mass per atom of an element from a given sample to 1 12 the mass of a carbon-12 atom The atomic number of the periodic table directly corresponds to the number of protons which is in the atom
- Atomic number | Definition Facts | Britannica
Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus Accordingly, the number of protons, which is always equal to the number of electrons in a neutral atom, is also the atomic number
- List of chemical elements - Wikipedia
118 chemical elements have been identified and named officially by IUPAC A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i e , a specific atomic number, or Z) [1] The definitive visualisation of all 118 elements is the periodic table of the elements, whose history along the principles of the periodic law was

Atomic number is a unique identifier to identify elements in the periodic table (2) Determines Chemical Properties: The atomic number plays a vital role in determining chemical behavior The number of protons and the number of electrons in a neutral atom affects how an atom interacts with others
- What Is an Atomic Number? Definition and Examples
The atomic number is important because it identifies the element Also, the periodic table is arranged in order of increasing atomic number The atomic number determines an element’s properties because its is the number of electrons in a neutral atom This defines the atom’s electron configuration and the nature of its valence electron shell
