					 What are the
 3 charges an
   atom can
     have?

+, -, and neutral.
Who was the man who
performed the “Gold foil
     experiment”?
        a. Dalton
      b. Rutherford
       c. Thomson
         d. Bohr
What were the 2 ideas that came
out of the Gold foil experiment?



      1.)All the positive in an atom is
   contained in a small densely packed
         place called the nucleus.
    2.) Atoms are mostly empty space.
What is the atomic number
        represent?




                   The number of
                    protons in an
                      element.
    If you are given an
elements mass and atomic
  number, how would you
    find the number of
 neutrons in the element?
 Subtract the mass from the atomic
              number.
Find the number of protons,
neutrons and elections for this
element, Cobalt (Co, Mass
number 59, Atomic number 27)




  Protons 27
  Neutrons32
  Electrons27
Who’s work is it, that leads
almost straight to the atom
          bomb?
   a. Chadwick/Rutherford
        b. Thomson
          c. Bohr
What is formed when an atom
 gains or loses an electron?
           a. An Ion
         b. A proton
          c. A Pony
         d. A neutron
Are atoms of the same
 element, the same?


  YES!!!!
Are you ready for the FINAL
      Question?!?!?!
If an element has eleven protons,
but only five electrons, what type
  of atom will it be and what is its
              charge?
     It would be an ion with a 6+
               charge.
