Manganese d configuration
Accepted Answer
Manganese (Mn) has an atomic number of 25, meaning it has 25 electrons. Its electron configuration is [Ar] 3d⁵ 4s². The d-orbitals are split into two sets of orbitals due to ligand field theory, resulting in a high-spin state for Mn²⁺ and a low-spin state for Mn³⁺.
