WebOct 26, 2024 · The core electrons for potassium are the 1s2 2s2 2p6 3s2 3p6 4s1. The reason that there are only 18 electrons in the core is because after the 1s orbital is filled, the 2s orbital has a slightly higher energy than the 2p orbitals. Therefore, the next electron goes into the 2s orbital rather than one of the 2p orbitals.
