The long hand electron configuration of manganese is: 1s22s22p63s23p64s23d5.
The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
The noble gas configuration for manganese (Mn) is [Ar] 3d5 4s2. This means that it has the same electron configuration as argon (Ar) with 18 electrons, followed by 3d5 and 4s2 orbitals filled with electrons.
The shorthand electron configuration of manganese is [Ar]4s^2 3d^5. This notation indicates that manganese has 25 electrons, with the last two in the 4s orbital and the remaining five in the 3d orbital.

The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
The element with this electron configuration is manganese (Mn), which has 25 electrons.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
[Ar]3d54s2

The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
The noble gas configuration for manganese (Mn) is [Ar] 3d5 4s2. This means that it has the same electron configuration as argon (Ar) with 18 electrons, followed by 3d5 and 4s2 orbitals filled with electrons.
The shorthand electron configuration of manganese is [Ar]4s^2 3d^5. This notation indicates that manganese has 25 electrons, with the last two in the 4s orbital and the remaining five in the 3d orbital.
The valency of manganese can be determined by looking at its electron configuration. Manganese typically forms compounds in which it has a valency of +2, +3, +4, +6, or +7 depending on the specific compound it forms. This valency corresponds to the number of electrons that manganese can lose or gain to achieve a stable electron configuration.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The long form electron configuration of tungsten is Xe 4f14 5d4 6s2.
Manganese's atomic number is 25. Thus it has 25 electrons. Filling in the first 25 orbitals gives the electron configuration of s2 2s2 2p6 3s2 3p6 4s2 3d5.
Manganese (Mn) contains 3d5 electrons in its ground state electron configuration.
