Study Notes
Domains of Chemistry
- Chemists study and describe the behavior of matter and energy in three different domains: macroscopic, microscopic, and symbolic.
Macroscopic Domain
- Refers to the realm of everyday things that are large enough to be sensed directly by human sight or touch.
- Includes everyday and laboratory chemistry.
- Physical and chemical properties such as density, solubility, and flammability are observed and measured in this domain.
Microscopic Domain
- Refers to the realm of small things that are not visible to the human eye.
- Some aspects of this domain are visible through standard optical microscopes, such as biological cells.
- More sophisticated instruments can image even smaller entities such as molecules and atoms.
- Other components of this domain include ions, electrons, protons, neutrons, and chemical bonds, which are too small to be seen.
Symbolic Domain
- Contains the specialized language used to represent components of the macroscopic and microscopic domains.
- Provides a way to describe and communicate chemical behavior using symbols, formulas, and equations.
