MATTER
ANYTHING THAT TAKES UP SPACE
MASS
THE AMOUNT OF MATTER IN A GIVEN SPACE
CONSERVATION OF MASS
MATTER/MASS CAN NEITHER BE CREATED NOR DESTROYED IN ORDINARY CHEMICAL REACTIONS
PHYSICAL CHANGE
A CHANGE WHERE NO NEW MOLECULE IS FORMED;
EX: HEAT, MELT, EVAPORATE,CONDENSE, AND SUBLIME
CHEMICAL CHANGE
A CHANGE WHERE NEW MOLECULE IS FORMED
EX: COLOR CHANGE, BURNING, GAS GIVEN OFF, PRECIPITATION
HETEROGENOUS MIXTURE
A MIXTURE WHERE SUBSTANCES ARE UNEVENLY MIXED
HOMOGENOUS MIXTURE
A MIXTURE WHERE SUBTANCES ARE EVENLY MIXED
MIXTURE
A PHYSICAL MIXING OF SUBSTANCES (MOLECULES REMAIN THE SAME...NO CHEMICAL REACTIONS)
EX: ROCKY ROAD ICE CREAM
MOLECULE
A CHEMICAL MIXING OF SUBSTANCES (NEW MOLECULES ARE FORMED...OLD ARE GONE)
COMPOUND
A MOLECULE THAT CONTAINS TWO OR MORE ELEMENTS
ELECTRON
PART OF THE ATOM WITH A NEGATIVE CHARGE
LOCATED IN THE ELECTRON CLOUD
MASS OF 0 amu

PART OF THE ATOM WITH A POSITIVE CHARGE
LOCATED IN THE NUCLEUS
MASS OF 1 amu
ATOMIC NUMBER
SAME AS NUMBER OF PROTONS IN AN ELEMENT
ATOMIC MASS
