Correct Electron Configuration for Chromium (Cr) Half-filled and fully filled subshell have got extra stability. So that molecule is more stable and less reactive nature. The symbol of manganese is Mn and its atomic weight is 54.938044 atomic mass units or grams per mole. By looking at an atom's electron configuration, it is possible to determine how many energy levels the atom has, how many electrons are in each energy level and how many electrons are in the atom's outer energy level. Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration) has the maximum number of unpaired electrons, all with the same spin. check_circle Expert Answer. Simply use this information to obtain its electronic configuration. See Answer. b. paramagnetic with one unpaired electron. Mn2+ electron configuration? Therefore, Mn2+ isa. Only the d4through d7cases can be either high-spin or low spin.
