WHAT DETERMINES THE CHEMICAL PROPERTIES OF AN ELEMENT?

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?

WHAT IS AN ISOTOPE?

ATOMS WITH THE SAME ATOMIC NUMBER, BUT DIFFERENT ATOMIC MASS (DIFFERENT NUMBERS OF NEUTRONS IN THE NUCLEUS).

WHAT IS THE DIFFERENCE BETWEEN A HETEROGENEOUS MIXTURE AND A HOMOGENEOUS MIXTURE?

WHAT IS THE DIFFERENCE BETWEEN A HETEROGENEOUS MIXTURE AND A HOMOGENEOUS MIXTURE?

WHAT IS THE DIFFERENCE BETWEEN A HYPOTHESIS AND A THEORY?

WHAT IS THE DIFFERENCE BETWEEN A HYPOTHESIS AND A THEORY?

A HYPOTHESIS IS AN UNTESTED IDEA, WHILE A THEORY IS A TESTED IDEA THAT HAS BEEN PROVEN TO BE CORRECT.

THE DENSITY OF A METAL IS 3.78 g/ml.

YOU HAVE 46 grams OF THE METAL. HOW MANY ml DO YOU HAVE.

THE DENSITY OF A METAL IS 3.78 g/ml.

YOU HAVE 46 grams OF THE METAL. HOW MANY ml DO YOU HAVE.

D = M/V or V = M/D = 46 g/3.78 g/ml

V = 12.2 ml
