For students taking Chemistry 101 at the University of Victoria in the Fall 2013 term.
When Ge loses 4 electrons it beomes Ge4+: [Ar]3p^10, but if it only lost 2 electrons would electrons leave the 4s orbital or the 4p orbital first?
4p; they're higher in energy than the 4s.
Go Canada! They're going to beat the all blacks...
Canada beating the All Blacks is about as likely as NZ beating Canada in ice hockey. Assuming there are enough people who know how to ice skate in NZ to actually form a team, of course...
Is there a list of recommended readings somewhere or is at alllll recommended?
The custom text IS your recommended reading. For Chem101, it's chapters 1 through 7.
is slaters rule going to come up on a midterm?
No, we don't teach Slater's rules explicitly, but you do need to understand that electrons in the same shell shield each other poorly, but that the core electrons do a pretty good job of shielding. Slater's rules essentially add numbers to these statements, but they're still just approximations and we'd rather you understand the concept than memorize some numbers.
question 8.45 on chapter 3 assignment:how do you determine which substance is molecular and which is ionic.
Look at the difference in EN. Large difference suggests ionic, unless the metal has a very high + charge (in which case the bonding becomes covalent).
