   What is atom in chemistry?

   • 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.

   Is atom a building block of matter?

   • An atom is fundamental building block of matter. It consists of protons, neutrons, and electrons. While it is not the smallest particle of matter, it is the smallest unit that cannot be broken by any chemical means. Atoms consist of protons, neutrons, and electrons.

   Is matter a molecule or atom?

   • Most matter consists of an agglomeration of molecules, which can be separated relatively easily. Molecules, in turn, are composed of atoms joined by chemical bonds that are more difficult to break. Each individual atom consists of smaller particles—namely, electrons and nuclei.

   Why is matter composed of atoms?

   • The matter is composed of minute particles known as atoms. Atoms are indivisible particles that can’t be destroyed or created through chemical reactions. All atoms of an element have identical chemical properties and mass whereas, atoms of different elements have different chemical properties and masses.

   Can atoms be divided into smaller parts?

   • Atoms can combine with other atoms to form molecules but cannot be divided into smaller parts by ordinary chemical processes. Most of the atom is empty space. The rest consists of three basic types of subatomic particles: protons, neutrons, and electrons. The protons and neutrons form the atom’s central nucleus.

   (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.
