For the complete electron configuration, we write the sublevel, 1s, and then count the number of arrows in it, 2, so it's 1s2.
00:10
We do the same thing for the remaining sublevels, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, and then 4p, 1, 2, 3, 4, 5.
00:33
This is the complete electron configuration as represented by the orbital diagram.
00:40
You're then asked to name the element.
00:43
The element, assuming it's neutral, has a total of the same number of protons as electrons.
00:54
These superscripts refer to the number of electrons...
