Pure substances, mixtures, and the IUPAC naming system.
An element is a pure substance consisting of only one type of atom. Compounds represent chemically combined elements.
This unit covers elements, homogenous/heterogenous mixtures, and the standard rules for writing and naming chemical formulas (IUPAC nomenclature).
Matter is classified based on purity and physical combination status.
•Elements: gold, oxygen (pure atoms).
•Compounds: water, carbon dioxide (chemically bonded elements).
•Mixtures: air, saltwater (physically mixed).
