MATTER IS COMPOSED OF
EXCEEDINGLY SMALL PARTICLES
CALLED ATOMS.
AN ELEMENT CONSISTS OF ONLY ONE TYPE
OF ATOM, WHICH HAS A MASS THAT IS
CHARACTERISTIC OF THE ELEMENT.
ATOMS OF ONE ELEMENT DIFFER IN
PROPERTIES FROM ATOMS OF ALL
OTHER ELEMENTS.
ATOMS ARE NEITHER CREATED NOR
DESTROYED DURING A CHEMICAL
CHANGE.
