Electron Config for period 5

Postby Melody Zhang 3L » Tue Oct 30, 2018 8:14 pm

Does anyone know if we need to memorize the patterns for electron configuration for period 5 and below? They differ from the exceptions in period 4, like chromium is 3d5 4s1 instead of 3d4 4s2, because in period 5, niobium is 4d45s1 instead of 4d3 5s2.

The TA and UA sessions I've been to just said that the only exceptions we need to know are chromium and copper.
