Further Explanation

Matter  

• 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.
