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. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper.
(Atom Definition) Atoms are defined as “the basic building blocks of matter”. Atom is the basic of all matter. They are very small and consist of even tinier particles. Neutrons, Protons, and Electrons are the basic particles making up the atom. They join together with other atoms and create matter. It takes many atoms to create anything.
Jul 14, 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.
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.

An atom is an extremely small piece of matter. All normal matter – everything that has mass – is made of atoms. This includes solids, liquids, and gases. The atom cannot be broken to parts by chemistry, so people once thought it was the smallest piece of matter that could exist.
atom, Smallest unit into which matter can be divided and still retain the characteristic properties of an element. The word derives from the Greek atomos (“indivisible”), and the atom was believed to be indivisible until the early 20th century, when electrons and the nucleus were discovered.
Jan 24, 2024 · Atoms are the tiny building blocks from which everything around us is constructed. It's amazing to think you can make anything out of atoms, from a snake to an ocean liner—but it's absolutely true! Let's take a closer look. Artwork: From the hair on your head to the t-shirt on your back, everything in the world is made of atoms.
