Classification of Substances
-
Heterogeneous Mixture: Requires only macroscopic properties for classification and identification.
-
Homogeneous Mixture/Pure Substance: Involves analyzing atomic structure to understand composition.
-
Pure Substance: Can be defined as an element or compound based on atomic knowledge; consists solely of elements or compounds.
-
Element: Composed of a single type of atom, fundamental building block of matter.
-
Compound: Consists of two or more different types of atoms which are chemically bonded in a fixed ratio, forming distinct molecules or formula units.
-
Homogeneous Mixture (Liquid): Often referred to as a solution, where components are uniformly distributed at the molecular level.
