Atom Definition
Atoms are defined as the smallest particle that can exist independently in nature and can participate in a chemical reaction. Atoms are the building block of all the matter in the universe. The word term “atom” is derived from the Greek word “Atmos” meaning indivisible. It was viewed that if we break the matter into smaller parts the smallest part so obtained is called the atom. But we know today that atoms can be further divided into fundamental particles.
What is Atom?
Atoms are tiny particles that comprise all the things in the known universe. Atoms of an element are responsible for all chemical reactions occurring in nature. We know that atoms are made up of three fundamental particles namely,
- Electrons
- Protons
- Neutrons
These particles are also called subatomic particles as they are found inside atoms. An atom is the basic building block of matter and all the thing around us is made up of combing atoms in different proportions. Let’s learn more about Atom, its constituents, and its structure in detail in this article.
