What is Chemistry?
- Chemistry studies the properties, composition, and transformations of matter.
- Critical to innovation, development of pharmaceuticals, agriculture, and environmental management.
Branches of Chemistry
- Organic Chemistry: Focuses on carbon-containing compounds and their reactions.
- Inorganic Chemistry: Examines substances not classified as organic, primarily non-carbon compounds.
- Physical Chemistry: Investigates the structure and changes of matter along with the energy involved.
- Analytical Chemistry: Identifies, separates, and quantifies components of different molecules.
- Biochemistry: Studies substances and processes in living organisms.
- Theoretical Chemistry: Uses math and computer modeling for chemical principles and compound properties.
- Agrochemistry: Applies chemistry in agriculture, food processing, and environmental remediation.
- Astrochemistry: Analyzes chemical compositions and reactions in celestial bodies.
- Cluster Chemistry: Focuses on clusters of atoms, bridging single molecules and solid matter.
- Combinatorial Chemistry: Relates chemistry to soil, air, water, and environmental impact.
- Geochemistry: Studies the chemical composition and processes of Earth and other planets.
- Green Chemistry: Develops chemical processes and products that minimize hazardous substances.
- Medicinal Chemistry: Relates chemistry to drug development and pharmacology.
- Nuclear Chemistry: Concerned with nuclear reactions and isotopes.
- Photochemistry: Studies the interaction of light with matter.
Historical Perspective
- Metallurgy began around 1000 B.C. with ore processing for ornaments and weapons.
- Greek philosophers introduced theories about matter's behavior around 400 B.C., suggesting four fundamental elements: fire, earth, water, and air.
- Demokritos and Leucippos proposed the atomos theory—matter is composed of indivisible particles, leading to the concept of atoms.
- Alchemy is the precursor to experimental chemistry, historically seen as a pseudoscience focusing on transmuting metals (e.g., lead to gold).
- Pythagoras proposed that the Earth is spherical and revolves daily on its axis.
- Aristotle expanded on elemental theories, integrating concepts of matter and transformation.
