Chemical elements listed by atomic number

Note that elements do not show a natural relationship between them, as the periodic system shows. You can find metals, semiconductors, non-metals, inert inert gases (ses), halogens, actinides, Act elements (rare earth elements) and transition metals.

As of November 2018, 118 chemical elements have been identified. A chemical element or element is an atomic species (that is, the same atomic number or Z) having the same number of protons in its nucleus. Hence, elements can be listed by the number of protons in the atoms of each element listed below.

Atomic number: The number of protons in an atom is called the atomic number of the element. The number of protons defines what it is and also determines the chemical behavior of the element. For example, a carbon atom has 6 protons, 1 hydrogen atom and 8 oxygen atoms. Atomic symbol: An atomic symbol (or element symbol) is an abbreviation that is chosen to represent an element ("C" for carbon, "H" for hydrogen, "O" for oxygen, etc.). These symbols are used internationally, sometimes accidentally. For example, the different name for this element is wolfram, so the tungsten symbol is "W". Furthermore, since the Latin word gold is gold, the atomic symbol of gold is "Au".

A chemical element is a pure substance composed of a single type of atom characterized by a specific number of protons in the nucleus called the atomic number represented by the symbol Z. The mass number is the number of protons and neutrons in the nucleus. All nuclei of all atoms belonging to one element have the same atomic number, but they do not necessarily have the same mass number, elemental atoms having different mass numbers are called isotopes. For example, all atoms in a nucleus containing six protons are carbon atoms of chemical elements, but the mass of carbon atoms is 12 or 13.
