Atoms All matter is composed of atoms. Atoms are often called the building blocks at matter
Element Matter that is made up of only one kind of atom
Is water an element? No, water contains two different elements – hydrogen and oxygen
Compound A substance is composed of the atoms of two or more different elements joined together chemically Scientists have identified more than 24 million compounds ******SO IS WATER A COMPOUND?
Water = H 2 0 Table Salt = NaCl Ammonia = NH 3 Baking Soda = NaHCO 3 Chalk = CaCO 3 Octane = C 8 H 18 *** Are these elements or compounds?
Molecule The smallest unit of a compound that retains the properties of a substance VS.
Atoms H Molecules H 2 (Diatomic)
Atoms O Molecules H20H20 ***MAKE SURE YOU COLOR CODE YOUR ATOMS – USE MARKERS AT TABLE
Atoms N Molecules NH 3 ***MAKE SURE YOU COLOR CODE YOUR ATOMS – USE MARKERS AT TABLE
