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.
mn
There is no element symbolized as "M". If you find M in a chemical formula or equation, it most likely means any metal element (i.e., iron, silver, etc). There are three metals which begin with M: magnesium (Mg), manganese (Mn) and molybdenum (Mo).

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
Manganese (Mn) contains 3d5 electrons in its ground state electron configuration.
The element with one 3d electron is manganese (Mn), which has the electron configuration [Ar] 3d^5 4s^2.
Mn
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 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 in question has an atomic number that is 2 less than element C and its electron configuration ends in 3d9. This would suggest that the element is one of the transition metals that comes before element C in the periodic table. A possible candidate fitting this description is manganese (Mn), which has an atomic number of 25 and an electron configuration of [Ar] 3d5 4s2.
The first-row transition metal with the most unpaired electrons is manganese (Mn). Its expected ground-state electron configuration is [Ar] 3d5 4s2, meaning it has 5 unpaired electrons in the 3d subshell.
The electron configuration of manganese (Mn) in the ground state is [Ar] 3d5 4s2, where [Ar] represents the electron configuration of argon. This means manganese has 25 electrons arranged in orbitals, with 5 electrons in the 3d orbital and 2 electrons in the 4s orbital.
The electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d7 represents the element manganese (Mn), which has an atomic number of 25.
