Nov 19, 2023 · An atom is the smallest unit of matter that forms a chemical element and cannot be divided using any chemical means. Learn about the structure, properties, and history of atoms, as well as the difference between matter and antimatter atoms.
An atom is the smallest unit of matter that retains all of the chemical properties of an element. For example, a gold coin is simply a very large number of gold atoms molded into the shape of a coin, with small amounts of other, contaminating elements.

Jan 9, 2020 · The atom is the smallest unit of matter that can't be divided using any chemical means and the building block that has unique properties. In other words, an atom of each element is different from an atom of any other element. However, even the atom can be broken into smaller pieces, called quarks.

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.
Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a chemical change.
