ExplanationMatter  Matter is anything that has weight and occupies space. Matter exists in three states, liquid, gases, and solids.For example, from the examples above; helium is matter in a gaseous state, water in liquid state and desk in solid-state.Matter is made up of small particles that are in continuous random movement.Particles  A particle refers to a single atom or a group of atoms that are bonded together and functions as a single unit.  Therefore, matter is made up of particles that can either be single atoms or chemically bonded atoms to make a molecule. Hence, a molecule is also a particle of matter.An atom  An atom is the smallest particle of an element that can take part in a chemical reaction.Atoms are made up of sub-atomic particles which include; protons, neutrons, and electrons. When two or more atoms are bonded together they form a molecule.Molecule  A molecule is the smallest particle of an element or a compound that has similar properties of that particular compound or element.Molecules could be made up of atoms that are similar such as oxygen molecules or atoms that different from different elements, such as water molecules.The bonding of atoms to form molecules occurs as a result of the sharing or transfer of electrons between atoms.
