Today we had our first lecture over atomic theory and radioactivity. I was attentive because i found it very interesting. We learned about Dalton's 5 postulates, the Law of Constant Composition and how to figure out the percentage of a given element in a compound. We also learned about JJ Thomson's cathode experiment and Rutherford's gold foil experiment and how it deflected alpha particles. we had a pre-test yesterday over the new unit. I feel as if I didn't do my best but i will definitely improve my score throughout the chapter.
Great post but... I would focus on making your posts and blog more professional and appealing to the reader. You can start by watching for grammar and spelling errors and have more complex sentence structure. Good Luck!
