- elements composed of atoms
- atoms of one element are identical
- atoms of different elements are different
- compounds consist of the atoms of different elements
- atoms indivisible and are not created/destroyed in chemical reactions
JJ Thompson(chocolate chip) JJ Thompson animation/information
- used cathode tube to show the atoms of any element emit particles with -charge
- electrons placed randomly in positive matrix

I did like it that you went further into depth on this, given that I cannot fully understand the cathode experiment executed by Thomson. Saying that, this is a good study tool for the exam tomorrow.
ReplyDeleteThis helped out so much for summarizing the main ideas of the different people with coming up ideas for atoms! I get confused between who thought what and whose models belong to who! This was short, simple, and sweet and that's the best part! Thank you for posting this!
ReplyDeleteI agree with Brianna. I like how you summarized each topic and I think that it makes it easy for readers to understand the information without having to read through details.
ReplyDeleteThese are very informative notes that will come in handy when studying for future tests over these subjects. Information is easily found and understood.
