16. Pure Substance: Made up of only ONE thing & has a CONSTANT COMPOSITION
Element:
Made up of ONE atom (one element from the periodic table!)
Cannot be broken down any further
EX: Carbon (C), Nitrogen (N), Oxygen(O), Sodium (Na)
Compound:
TWO or more atoms chemically combined (molecule)
Can be chemically broken down into individual atoms
Definite ratio of elements in the compound
EX: Water (H2O), Salt (NaCl), sugar (C6H12O6)

17. Mixture: Made up of TWO or more substances (amount of each substance doesn’t matter) that can be physically separated
Homogeneous:
Substances are mixed EVENLY throughout
Looks the “same”
EX: Sugar Water, Salt Water, Kool-aid
Heterogeneous:
Substances are NOT evenly distributed
Looks “different” throughout
EX: Concrete, Dirt, Pond Water
