Need help asap, Rh electrons
« on: January 25, 2018, 12:25:43 PM »
Does anyone know why Rh has 8 electrons on 4d, and 1 on 5s, as I know those layers complete with n+l rule, and for 4d it's 4+2=6 and for 5s it's 5+0=0 so 5s should complete first, but Rh has 4d^8,  5s^1, anyone explain please

Not everything goes according rules, check chromium or copper for example.
