Today we continued on with our reading of lesson 1 of chapter 10 from the text book. We read from pp. 347-349. Here we as seeing how all the parts of the Periodic Table came to be and then how to use the Periodic Table. We looked at how the columns on the table are the groups or families that have the same traits. We learned that the periods are the rows on the periodic table. These same rows also tell us how many Bohr shell are required for that shell. We then saw how the Periodic Table's repetitive pattern can be used to predict future elements. Finally on the bottom of our written out student Periodic Table, we wrote down:
K= 2 --> shell 1
L= 8 --> shell 2
M= 18 --> shell 3
N= 32 --> shell 4
This tell us how many possible electron can be found on each shell.
We then took time to view the video Hunting the Elements from Nova. here we looked at time stamp :41 to :48. This does a great job of explaining how electrons rule the reactivity of elements.
Please read the above pages again if you need a bit more clarification.
If you are still confused, below are three videos on the Periodic table and how to use it.
