May 20, 2024 · Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms.
Nov 19, 2023 · An atom is the basic building block of matter, consisting of protons, neutrons, and electrons. An atom is the smallest unit of matter that forms a chemical element and cannot be divided using any chemical means. Every solid, liquid, gas, and plasma consists of neutral or ionized atoms.
