Electron Configuration

Postby melissa_dis4K » Fri Nov 02, 2018 1:05 am

When finding the electron configuration for Cerium, it is [Xe] 4f^1 5d^1 6s^2, I understand the 5d^1 and 6s^2, however I am confused on where and how we get 4f^1. I'm just confused on how to find it for the f-block. I know that for the d-block we have to take the period and subtract one is there something similar happening here?

The f- block are the elements that are outside the periodic table, but they go between La (57) and Ha (72). You can just look at the periodic table.
