Shorthand electron configurations Recall that we can indicate position of electrons via orbital diagrams or electron configurations. Fitting 100 or more electrons into this pattern becomes cumbersome. We can write shorthand electron configurations… Read remainder of 6.7 (pg. 206 - 207). PE 7.

Shorthand electron configurations Because electrons fill orbitals in a regular pattern, we can shorten the work of writing electron configurations by using the preceding noble gas as a template We write the highest shell last to indicate the “valence electrons” - i.e. those furthest out (involved in bonding and chemical reactions) We can represent shorthand electron configurations of the noble gasses 2 ways: E.g. Ar = 1s 2 2s 2 2p 6 3s 2 3p 6 = [Ne]3s 2 3p 6 = [Ar] Use [Ne]3s 2 3p 6 for this course
