Study Notes
Overview of Chemistry
- Chemistry studies matter, its properties, composition, structure, and changes it undergoes during chemical reactions.
- Occupies an intermediate position among sciences, connecting physics and biology by focusing on the molecular and atomic bases of physical phenomena and biological systems.
Functions of Chemistry
- Explains the formation and behavior of substances at an atomic and molecular level.
- Provides a foundation for understanding various scientific disciplines, including biology, environmental science, and materials science.
Chemical Compounds and Molecules
- Addresses the arrangement and interaction of atoms within chemical compounds, exploring how they affect properties and behaviors.
- A molecule is defined as a group of two or more atoms held together by chemical bonds.
- A monatomic molecule consists of atoms of a single chemical element, such as helium (He) or neon (Ne).
- In the kinetic theory of gases, the term 'molecule' often refers generically to particles, which can include atoms or combinations of atoms.
- A chemical compound that consists of more than one element is designated as a molecular compound.
- Ionic bonds are typically not considered as part of a single molecule since they involve the electrostatic attraction between charged ions rather than specific bond formation between atoms.
