8. RUTHERFORD DISCOVERED THE NUCLEUS

9. TYPICAL TEXTBOOK VERSION OF ATOM Nucleus: A) Protons – positive charge (big) B) Neutrons – neutral charge (big) Flying around the outside – A) Electrons – negative charge (tiny) 2 in the first shell 8 in each shell thereafter – sort of MOSTLY EMPTY SPACE

10. ALL MATTER IN THE UNIVERSE IS MADE FROM THREE PARTICLES! Sentence with three letters of the alphabet? Sentence with three letters of the alphabet? MY NAME IS BILL. MY NAME IS BILL. I, O, B I, O, B

11. ELECTRON CLOUD MODEL Electrons flying around fast – all we can do is visualize where they probably are. Atoms act AS IF the electrons are everywhere. But if you look, they jump to one place.

12. COOL FACTS ABOUT ATOMS 1) All of the matter in the human race can fit in a sugar cube. 1) All of the matter in the human race can fit in a sugar cube. 2) Electrons move from one level to another; they don’t jump – they disappear and reappear. 2) Electrons move from one level to another; they don’t jump – they disappear and reappear. 3) E=MC2 – Ultimately energy and matter are the same! 3) E=MC2 – Ultimately energy and matter are the same! 4) There are 100 trillion atoms in a typical human cell (100,000 billion) 4) There are 100 trillion atoms in a typical human cell (100,000 billion) http://www.youtube.com/watch?v=yQP4UJhNn0I http://www.youtube.com/watch?v=yQP4UJhNn0I http://www.youtube.com/watch?v=yQP4UJhNn0I

13. EXTRA CREDIT OPTION An A for every student in the class if you write for me on paper 1 billion Xs. An A for every student in the class if you write for me on paper 1 billion Xs. Let’s do the math… Let’s do the math… How many Xs in one hour? How many Xs in one hour? One day? One day? One week? One week? One year? One year?
