Study Notes
Definition of Molecule
- A molecule is a group of atoms that are chemically bonded together.
Fields where Molecule is Interchangeable with Polyatomic Ions
- The term 'molecule' is often used interchangeably with polyatomic ions in the fields of chemistry and physics.
Types of Molecules
- A molecule that consists of atoms of one chemical element is called an atomic molecule.
Kinetic Theory of Gases
- In the kinetic theory of gases, molecules are often referred to as particles that are in constant motion.
Historical Contributions
- The famous scientist who contributed to the study of molecules in the 17th century is Robert Boyle.
- The study of molecules is known as molecular science or molecular chemistry today.
- The ancient Greek philosopher who argued that all the universe is composed of atoms and voids is Democritus.
- Robert Boyle proposed the idea that matter is composed of particles that are too small to be seen in his treatise The Sceptical Chymist.
- The French chemist who published views on combinations of 'ultimate' particles in 1789 is Pierre Macquer.
- The French chemist who is credited with creating the word 'molecule' is Jean Baptiste Perrin.
Ancient Greek Philosophers
- Empedocles imagined the fundamental elements of the universe as earth, air, fire, and water.
- Amedeo Avogadro stated in his 1811 paper that equal volumes of gases at the same temperature and pressure contain an equal number of molecules.
- The modern concept of molecules can be traced back to the work of Amedeo Avogadro.
- Aristotle accepted the concept of four fundamental elements (earth, air, fire, and water) and passed it to medieval and renaissance Europe.
