ATOMS!

Well this week we focused on learning about atoms. Atoms are really really small. We saw a video on powers of 10 which really showed us how small atoms are (and also how big the universe is). There was the Simpsons parody of it that we watched today; that was pretty cool and funny. Earlier this week though, we learned how to tell how many protons, electron, and neutrons are in an atom. The atomic NUMBER shows the number of protons which is equal to the number of electrons. Also, the atomic MASS is the total from adding the number of protons to neutrons! We learned about ionic compounds and what the different groups in the periodic table tell about the elements that are in that column. We did a lot of notes, review questions, and worksheets on all of this.
