Atomic Structure
Yesterday, we learned about Dalton's Atomic Theory, and that not all of his theory is still true today. We practiced calculating the percent composition, also known as the proportion of mass. Thomson used a cathode ray tube in order to show atoms of any element emit particles with a negative charge. We learned about Rutherford and his gold foil, he gave us the proton. The current Atomic Model is a "cloud model", meaning that there are no distinctive boundaries.
