1. Particle Diagrams Elements: one type of atom (single or diatomic)
Compounds: 2 or more types of atoms bonded together
Mixtures: combination of elements and/or compounds
Homogenous: uniform particles throughout
Heterogeneous: particles are not dispersed evenly; may see layering

2. Particle Diagrams Elements: one type of atom (single or diatomic)
Diatomic Elements: elements that exist as pairs in nature
