Is 1s22s22p6 the image for a macroscopic property or a microscopic property of an element?
The 1s orbital is full, the 2s orbital is full, and there are 4 electrons to draw within the 3 boxes in the 2p orbital. As per Hund’s Rule, there could be 3 arrows pointing up in the 2p orbital and 1 pointing down. So there is a pair of electrons within the first box of the 2p only. The concept is to draw an arrow for each electron, so on this case we now have two arrows to attract.
And then they’ll start double occupying of orbitals of subshell. That is the rationale, we observe four different atomic orbitals across the nucleus of an atom. Note this could be a special case that Hund’s Rule doesn’t really matter, since the 2p and 3p packing containers are completely full of arrows. It doesn’t matter what order they’re drawn, since they’re just full.
The first 18 electrons fill as for Argon Ar within the previous example. Next comes the 4s orbital, which is full with 2 electrons. The arrows at all times fill from bottom up, so the 2p comes subsequent. Note the 3s is actually above the 2s, but the 2p is the subsequent highest electron orbital to fill. For understanding the whole picture of atomic spectra of parts in the periodic table. Hence, unabbreviated electron configuration remains for a lot longer, confused and time-taking.
