1

he is British
"all matter is made up of atoms"
"all atoms of an element are exactly alike"
"matter is neither created nor destroyed"

Dalton

2

he realized + & - charges in atoms
believed whole atom was solid with positives
"-" = "electrons"
(((Plum Pudding Model)))

J.J. Thomson

3

he propelled alpha particles through gold foil
-some bounced
-some went backwards
-some hit the nucleus & bounced straight back
"atom = empty space"

Rutherford

4

he was german
"in an element, light is given off or absorbed as packets of energy"
these packets are quantized, come in different sizes

Max Plank

5

Max Plank & Albert Einstein = ....

Quantum Theory

6

he said every electron has a fixed orbit
"every electron has a location"
"every orbit has a # of electrons"
"farther from the nucleus, the more energy it takes to stay in the orbit"

Bohr

7

he said that we can know the location and momentum of the electron, but not at the SAME TIME
he published "Heisenberg Uncertainty Principle"

Heisenberg

8

They both said that we don't know exactly the location of an electron
you can know the probability of the area where it should be

14

what is Heisenbergs model of the atom?

spheres in each other, w/ electrons on the lines, and nucleus in middle

15

what is Schrodinger and Bohr's model of the atom?

three lines from nucleus (level 1,2,3)
electrons on each energy level
protons in nucleus

16

he was a greek philosopher
cutting object in half
^called tis the atomus
he said it was round and plain
his idea disappeared, so did he.

Democritus
