“Are we seriously just organizing things” – A student in 5th period
Not quite! Today we used our knowledge of periodic trends to organize unknown elements into groups based on chemical and physical properties, so that by looking anywhere on the table you could guess the properties of the unknown element.
. . . Which is exactly how the real periodic table is set up! Remember a few trends, and you can predict how most elements are going to react.
Aim: How can periodic trends be used to classify unknown elements?
Homework: Complete the periodic table assigned. Write a 1-page (handwritten) explanation of why you organized the table in the way that you did.
