Students started class with a BrainPop and a worksheet related to Atoms. Scores were very high in all three portions of the competition.
2 can go on the first ring (corresponding with the 2 elements on the first period of the periodic table). If you look at all the models to the left, they all only have 2 electrons on the first ring near the nucleus. 8 go on the 2nd ring, just like there are 8 elements in the 2nd period. The next ring gets 18.
The D block is dumb and that's why it starts with one number lower. Really they just have less energy and have the same amount of energy as the S and P block in the 3rd period. The F block are failures and that's why they are 2 lower... or they have a lot less energy.
Students practiced identifying the energy level, orbital, and location of elements on the periodic table. For example Carbon is a 2P2 because it is in the 2nd period, in the P block, and the 2nd one over in the P block.
