Study Notes
Molecules and Atomic Theory
- A molecule is a group of two or more atoms that are chemically bonded together.
Homonuclear and Heteronuclear Molecules
- A homonuclear molecule is a molecule composed of atoms of the same element.
- A heteronuclear molecule is a molecule composed of atoms of different elements.
Kinetic Theory of Gases
- In the kinetic theory of gases, the term 'molecule' is often used to describe the smallest unit of a gas that retains the physical and chemical properties of that gas.
Interactions and Single Molecules
- Ionic interactions and hydrogen bonds are typically not considered as single molecules.
Contributions to Atomic Theory
- Amedeo Avogadro, during his work on gas volumes, contributed to the modern investigation into the nature of molecules and their bonds.
- Robert Boyle argued that matter's basic elements consisted of clusters of particles.
- Empedocles imagined fundamental elements (fire, earth, air, and water) and 'forces' of attraction and repulsion allowing the elements to interact.
Origin of the Word 'Molecule'
- The word 'molecule' was created by Laurent Auguste in 1801.
- The word 'molecule' became popular in the 19th century, specifically in 1811, after being used in works of philosophy by Descartes.
- Early definitions considered molecules to be small, indivisible particles that cannot be broken down further.
Ancient Philosophers
- Leucippus and Democritus argued that the universe is composed of atoms and voids.
- Epicurus accepted the viewpoint of Leucippus and Democritus, which was later passed to medieval and renaissance Europe through Aristotle.
- Empedocles considered the fundamental building block of the heavenly bodies to be the four elements: fire, earth, air, and water.
