The element that contains five electrons in its 3d orbital is manganese (Mn). Manganese has an atomic number of 25, and its electron configuration is [Ar] 4s² 3d⁵. This means it has five electrons in the 3d subshell.
In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
Manganese has 25 electrons. Hope this helps. :)

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 orbital diagram for manganese (Mn) in its ground state would show the distribution of its 25 electrons among the available orbitals according to Hund's rule and the Aufbau principle. The electron configuration for Mn is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^5. This would be represented in an orbital diagram as having two electrons in the 4s orbital and five electrons in the 3d orbital.

Mn2+ has 25 electrons. Mn2+ means that the manganese atom has lost two electrons, resulting in a +2 charge. Mn is the symbol for manganese, which has an atomic number of 25, indicating that it normally has 25 electrons in its neutral state.

The Bohr diagram for Mn shows 4 rings because manganese has 25 electrons. Following the rule of placing 2 electrons in the first ring, 8 electrons in the second ring, 8 electrons in the third ring, and the remaining 7 electrons in the fourth ring gives a total of 25 electrons distributed in the 4 rings.
