Atoms (Elements) Molecules & Compounds

Atom, Molecule or Compound?

ATOM Smallest unit of matter Smallest unit into which an element can be divided and still be the same substance ELEMENT = type of atom

Molecule 2 or more atoms bonded together  Can be the same type of atom = molecule of an element  Can be different types of atoms = molecule of a compound

Compound 2 or more atoms of different elements bonded to form a new substance with new properties

Compound 2 or more atoms of different elements bonded to form a new substance with new properties Example: _____________ H = colorless, odorless flammable gas O = colorless, odorless flammable gas H 2 O = colorless, odorless nonflammable liquid water = H 2 O

Classify the following as Atoms, Molecules, Compounds Element – type of atom 2 or more different atoms bonded Note: All compounds are molecules, but not all molecules are compounds
