Jul 14, 2024 · An atom is the basic building block of chemistry. It is the 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.

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.

Atoms are the smallest units of elements that still retain the element's properties. Atoms contain electrons, neutrons, and protons. Each element is defined by the number of protons in its nucleus.

Atoms are the smallest unit that matter can be divided into without the release of electrically charged particles. Atoms are actually made up of three types of particles: positively-charged protons, neutral neutrons, and negatively-charged electrons.
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 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.
Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds.
