What is an Atomic Number?

The atomic number refers to the ordinal number of the element in the periodic table, the symbol is Z, and it is numerically equal to the nuclear charge number (that is, the number of protons) of an atomic nucleus or the number of electrons outside a nuclear atom. For example, the atomic number of carbon is 6, and its nuclear charge number (proton number) or the number of electrons outside the core is also 6. ^[1]

Atomic number is one

Each chemical element has unique chemical properties depending on the number of electrons (that is, the atomic number) when its element is electrically neutral. Electronics

Newly discovered elements are generally represented by their atomic order. As of 2010, elements with atomic numbers 1 to 118 have been found. The synthesis of a new element is to hit a target atom with a high atomic order with ions, and the atomic sum of the ions and the target atom is equal to the atomic order of the element to be found. Generally speaking, when the atomic order is larger, its half-life is shorter, but there may be stable islands for isotopes of a specific number of protons and neutrons, and its half-life will be longer than elements with the same atomic order. ^[1]
