Question 5 on test 1

I think in the future we will have a much more complicated model of the atom. Right now our atom includes the proton, nuetron, and electron. I think in 3,000 the atomic model will still be made of protons, neutrons, and electrons. Protons and Neutrons are made of quarks and gluons, but what are they made of?    Electrons are made of electrons but I don't think that something can be made of itself.  What is the root of electrons?  If the root of electrons is electrons than electrons are made of electrons and those electrons are made of other electrons and so on.  Who knows if all that is true?  The world keeps on getting smarter and smarter.  If science continues it's pattern then the atomic model will change in between now and 3,000.  But if the worlds going to end in 2012 then we won't get to 3,000.

Question 2 on test 1

We know about electrons even though they are extremely small. Ernest Rutherford did the Gold Foil Experiment in the early 1900s.  Rutherford fired alpha particles at the gold foil and most went through the gold foil but some bounced off at sharp angles. This experiment and many others like it concluded that atoms had both positively and negatively charged particles. This experiment and many others like it and other chemical and nuclear reactions that there are definitely electrons, protons, and neutrons.
