COMPOUNDS: FAIL INTO 2 CATEGORIES: MOLECULA + NON MATAL.
EXAMPLE: CO2, H2O ION: METAL + NON METAL
EXAMPLE: NaCO IONS CHARGE ATOMS ( +CATION /ANION - ) METALS ARE USUALLY CATION NON METALS ARE ANION |

LAW OF DEFINITE COMPOSITION:
ALWAYS CONTAINS 2 OR MORE ELEMENTS CHEMICALLY COMBINED IN A DEFINE PROPORTION BY MASS.

|
LAW OF MULTIPLE PROPORTION: ATOMS OF TWO OR MORE ELEMENTS MAY COMBINE IN DIFFERENTIATION TO PRODUCE MORE THAN ONE COMPOUND. EXAMPLE: H O H2O = WATER H2O2 = PEROXIDE |
LAW OF MULTIPLE PROPORTION:
ATOMS OF TWO OR MORE ELEMENTS MAY COMBINE IN DIFFERENTIATION TO PRODUCE MORE THAN ONE COMPOUND.
EXAMPLE: H O H2O = WATER H2O2 = PEROXIDE |
