The electron configuration of potassium is 1s22s22p63s23p64s1, according to the University of Maryland website. Potassium has a total of 19 electrons, but these electrons are arranged in four different energy levels.Know More
Each energy level has one or more orbitals where electrons reside. In one atom of potassium, the first energy level has two electrons in the s orbital. The second energy level has a total of eight electrons. Two of the electrons are in the s orbital and six are in the p orbital.
The third energy level also has electrons in the s and p orbitals. There are two in the s orbital and six in the p orbital, the same as in the second energy level. Finally, the fourth energy level has one electron in the s orbital.Learn more about Atoms & Molecules
The electron configuration for manganese is 1s2 2s2 2p6 3s2 3p6 4s2 3d5. It can be shortened to [Ar] 4s2 3d5, where the [Ar] represents argon, the last element in the third row of the periodic table, whose electrons fill every shell prior to the 4s-orbital.Full Answer >
