Transcript What are the 3 charges an atom can have?

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.
