ATOMS VOCABULARY Fill in your vocabulary chart or review your notes as you view the powerpoint

 ATOM  SMALLEST UNITS OF MATTER  CANNOT BE BROKEN OR DIVIDED APART  TOO TINY TO SEE EXCEPT WITH POWERFUL MICROSCOPE

 NUCLEUS  CENTER OF AN ATOM  PROTONS AND NEUTRONS ARE IN THE NUCLEUS

 PROTONS  IN THE NUCLEUS OF ATOM  HAS A POSITIVE CHARGE +

 NEUTRONS  IN THE NUCLEUS OF ATOM  HAS NO CHARGE….NEUTRAL

 ELECTRONS  ORBIT OR CIRCLE AROUND THE NUCLEUS VERY QUICKLY  HAVE A NEGATIVE CHARGE -  NEGATIVE AND POSITIVES CHARGES ATTRACT TO MAKE THE ATOM WORK. PROTONS & ELECTRONS CREATE THE CHARGES OF ATOMS.  ELECTRONS

DIFFERENT MODELS

ANSWER THESE QUESTIONS  1. WHAT IS AN ATOM?  2. WHAT IS THE NUCLEUS?  3. WHAT TWO PARTS ARE IN THE NUCLEUS?  4. WHAT PART ORBITS AROUND THE NUCLEUS?  5. WHAT ARE THE CHARGES OF EACH PART?
