The weekend is over. We are now in 3.091. So, announcement: this Wednesday there will be no lecture, instead, celebration of learning: test number two. These are the room assignments. We moved them just a little bit, moved the dividing lines, rather. It's the same rooms, but we wanted to make a little more room in here and in the Walker gym. So, there are more people being asked to go to room 1-190. And then, this is the group to go to the Walker gym, third floor of the Walker Memorial building.

And, if you can't get them during that time, there's no expiry. You can get the grade change at some later date. And, we'll make sure we fix things up. So, last day we were talking about covalent bonding, looking at linear combinations of atomic orbitals into molecular orbitals. And, we saw that there's two types of molecular orbitals involving s and p-block elements that are germane to us. We are not going to go into d-block in any deta...
