To write the electron configuration for Ar (argon) with 4s^2 and 3d^1 in longhand, you first write the electron configuration for argon (Ar): 1s^2 2s^2 2p^6 3s^2 3p^6. Then, you add the additional electrons in the 4s and 3d orbitals: 4s^2 3d^1.
In Fe atoms, the 3d orbitals are partially filled. Iron (Fe) has an electron configuration of [Ar] 3d^6 4s^2, where the 3d orbitals contain 6 electrons.
The 4s orbital is a type of atomic orbital that is part of the fourth energy level in an atom. It has a spherical shape and can hold up to 2 electrons. The 4s orbital is lower in energy than the 3d orbital in the periodic table.
The ground state shorthand notation for iron (Fe) is [Ar] 3d^6 4s^2.
