Electron Configuration Chart Order. Hydrogen and helium are placed somewhat arbitrarily. Based on the fill order above, these 8 electrons would fill in 1s, 2s and then 2p in the following order.
This handy chart compiles the electron configurations of the elements up through number 104. 1s 2 2s 2 p 6 3s 2 3p 2 Although hydrogen is not an alkali metal, its 1s 1 electron configuration suggests a similarity to lithium ([he]2s 1) and the other elements in the first column.although helium, with a filled ns subshell, should be similar chemically to other elements with an ns 2 electron configuration, the closed principal shell dominates its chemistry.
Your first example of loading is the one that will come off the aufbau chart.

These are the numbers that students' in. Nevertheless, check the complete configuration and other interesting facts about molybdenum that most people don't know.
