chemical element

Also known as element, atomic element, chemical elements

species of atoms having the same number of protons in the atomic nucleus and the same chemical properties, but not necessarily the same mass, or the same stability (or half-lifetime if they are unstable)

AI overview

A chemical element is a type of substance made up of atoms that all have the same number of protons in their nucleus and behave the same way chemically, even though individual atoms of that element might have different masses or levels of stability. Chemical elements matter because they are the fundamental building blocks of all matter, and understanding them helps us identify and predict how different substances will interact with each other.

The chemical elements ordered in the periodic table, as shown in the 32-column format

A chemical element is a species of atom defined by its number of protons. The number of protons is called the atomic number of that element. For example, oxygen has an atomic number of 8: each oxygen atom has 8 protons in its nucleus. Atoms of the same element can have different numbers of neutrons in their nuclei, known as isotopes of the element. Atoms of one element can be transformed into atoms of a different element in nuclear reactions, which change an atom's atomic number. Almost all baryonic matter in the universe is composed of elements (among rare exceptions are neutron stars).
