ATOM:
- An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons
MOLECULE:
- Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
PARTICLE:
- In the physical sciences, a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.
COMPOUND:
- A compound is a substance that contains atoms of two or more different elements, and these atoms are chemically joined together.
MIXTURE:
- A mixture is created when two or more different substances are physically combined and can be separated back into its original substances.
