In class Feb 6, we looked for any misunderstandings or problems with material in 2.1 and 2.2. We were going to talk about mass spectrometres and isotopes and calculations but 8 people are away, so we’ve saved that for Wednesday Feb 15th.
Today we did this activity on patterns in Ionization energies, and why that is evidence for the organization of electrons. If you are not here, you should do it!
Our next lesson, on Feb 13th, we will talk about trends in the periodic table, discussed in 3.1 and 3.2 in the text.
