• About a million atoms stacked on top of each other = the thickness of a sheet of paper.


• About 5 million atoms make up a period at the end of a sentence.


• Journal Question?


• Journal Question? – Please use the round Petri-dish to create a circle.

the universe.– I unfortunately must use simple pictures

because as we know atoms are very small and they are mostly empty space.

bonded together.

• An atom has charged particles, this means it has a (+) and a (-) charge.


• An atom has charged particles, this means it has a (+) and a (-) charge. – Atoms and some of the particles they are

made of carry a charge.

• Early experiments realized that that atoms were charged particles. One of those experiments is a Crookes tube.

worked to help show that atoms carry a charge.– http://www.youtube.com/watch?v=XU8nMKkzbT8

• Knowing that an atom had a charge was just the first step. Scientists still didn’t know the structure of the atom.


• Knowing that an atom had a charge was just the first step. Scientists still didn’t know the structure of the atom. – J.J. Thompsons early plum pudding model of

an atom.

• Ernest Rutherford’s experiment used particles and reflection to determine the structure of the atom.– What is the mystery shape in the next slide, using your

knowledge of reflection?


• Ernest Rutherford’s experiment used particles and reflection to determine the structure of the atom.– What is the mystery shape in the next slide. Use your

knowledge of reflection?


• Try and guess the mystery shape below based on how objects would reflect off it.


• Answer!


• Ernest Rutherford had to make sense of a puzzle similar to this to figure out the structure of the atom.






Rutherford’s gold foil experimentRutherford’s gold foil experiment


• Video! Rutherford’s Gold Foil Experiment


• In Rutherford's experiment, a radioactive source shot a stream of alpha particles at a sheet of very thin gold foil which stood in front of a screen.


• In Rutherford's experiment, a radioactive source shot a stream of alpha particles at a sheet of very thin gold foil which stood in front of a screen. – The alpha particles would make small flashes of light

where they hit the screen.


• Since some of the positive alpha particles were substantially deflected,


• Since some of the positive alpha particles were substantially deflected, Rutherford concluded that there must be something inside an atom for the alpha particles to bounce off of,


• Since some of the positive alpha particles were substantially deflected, Rutherford concluded that there must be something inside an atom for the alpha particles to bounce off of, that must be small, dense, and positively charged.
