THE AVERAGE KINETIC ENERGY OF AN OBJECT IS DIRECTLY PROPORTIONAL TO ABSOLUTE TEMPERATURE__.
ELEMENTS ARE COMPOSED OF ___________________________________.
COMPOUNDS ARE COMPOSED OF _TWO OR MORE ATOMS CHEMICALLY COMBINED (MOLECULES)______.
WHAT DETERMINES THE CHEMICAL PROPERTIES OF AN ELEMENT? THE ATOMIC NUMBER, Z, WHICH IS EQUAL TO THE NUMBER OF PROTONS IN THE NUCLEUS (ALSO THE NUMBER OF ELECTRONS IN SHELLS ABOUT THE NUCLEUS)
WHAT IS AN ISOTOPE? ATOMS WITH THE SAME ATOMIC NUMBER, BUT DIFFERENT ATOMIC MASS (DIFFERENT NUMBERS OF NEUTRONS IN THE NUCLEUS).
