Study Notes
What Chemistry Studies
- Chemistry studies the composition, properties, and reactions of matter
- It examines the building blocks of matter (atoms and molecules) and how they interact
Position of Chemistry Among Sciences
- Chemistry is situated at the intersection of physics and biology
- It draws on principles from physics to understand the behavior of atoms and molecules
- It applies biological principles to understand the chemical processes in living systems
Composition of Compounds
- Compounds are made up of two or more different elements, chemically bonded together
- The properties of a compound are different from those of its individual component elements
Why Chemistry is Called the Central Science
- Chemistry connects and underlies other sciences, including physics, biology, and medicine
- It provides a molecular understanding of processes and phenomena in these fields
Role of Chemistry in Pharmacology
- Chemistry explains how drugs (pharmaceuticals) interact with the body
- It helps design and develop new medications, and understand their mechanisms of action
