22 September Announcements Practice exam tonight A103 : this room 7 – 9 pm Early Check In the gradebook on RamCT S vs. U After every exam Configuration of groups Take note of similar configurations within a group Group 8A – Noble Gases He, Ne, Ar All have full shells Group 1A – alkali metals Li, Na, K All have one electron in their outermost shell Group 4A – carbon group C, Si All have 4 electrons in their outermost shell Their common configurations → similar reactivity, give the reason for the periodicity seen among the elements Connection to the periodic table The table is constructed around electron configurations Periods → energy shells Atoms generally grouped by sublevel S block vs. p block vs. d block vs. f block Sublevels are ordered by their energy level Top down as you read Careful of 3 d elements on down Helpful mnemonic to remember order What can be filled for each n? Clicker question What is the correct electron configuration of Ge? 10 2 2 A. [Ar] 3d 4s 4p (wrong orbital order) B. [Ar] 4s 4p (missing 3d) 10 2 2 C. [Kr] 3d 4s 4p (wrong noble gas & wrong order) 2 10 2 D. [Ar] 4s 3d 4p * E. [Kr] 4s 3d 4p (wrong noble gas) Transition metals Follows auf
