100
Bohr's model introduced that electrons move in what way and around where?
In orbitals around the nucleus
100
What does atomos mean?
Not to be cut
100
What is the name of one of the model's Thomson constructed?
Plum Pudding Model
100
What does the Quantum Model show?
It shows the probability of where you can find an electron.
100
Aristotle and Plato thought that all matter was made of these four elements.
Earth, wind, fire, and water
200
How many electrons can be placed on the first orbital?
2 e-
200
Democritus a ________ philosopher who began the search for an explanation of matter.
Greek
200
Dalton thought that all elements were proposed of what?
Atoms
200
Do electrons spin the same way in the magnetic field? If not what is used to show they are spinning in opposite directions?
No they do not spin the same way in a magnetic field. Electrons spin clockwise and counterclockwise, represented by arrows.
200
What experiment did Rutherford Conduct?
Gold Foil test thingy magigy...
300
How many electrons can go on the first orbital?
32 e-
300
What did Democritus think atoms were?
Democritus thought atoms were hard small particles that were made of the same material that couldn't be cut.
300
Thomson thought that all positive energy lied in the middle, and the negatively charged energy was where?
Scattered around the outside (as shown in the plum pudding model)
300
What is the name of the four orbital subshells?
S, P, D, & F
300
What did the gold foil test show?
It showed that matter has empty space
400
Why did Bohr's model fail?
His model failed because it could only be used for one element.
400
Was Democritus' theory remember or forgotten over time?
His theory was ignored and forgotten.
400
Thomson also studied the passage of electric current through gas using what?
The Cathode Ray
400
What shape are subshells S and P?
S shell is spherically shaped, and P level is dumbbell shaped.
400
What did Rutherford's experiment involve?
It involved firing a stream of positively charged particles at a thin sheet of gold foil.
500
What is the only atom that Bohr's model could represent?
Hydrogen
500
What was the one question that Democritus asked about matter?
He asked if matter could be divided indefinitely or was there a limit.
500
As the electric current passed through the Cathode Ray it gave of ____________ charged rays, this surprised Thomson because the gas was _________?
negatively: uncharged
500
How many electrons can each INDIVIDUAL subshell hold?
2 electrons, each with a different spin.
