Electronic configuration of Cr2+ is [Ar]3d4 4s0. Electronic configuration for Fe2+ is [Ar]3d6 4s0. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons. Lv 7. In recent years, work in this quite “hot” research field has focused on the developme Recent Review Articles Answer to: Draw the electron configuration and condensed electron configuration for Mn2+. 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. The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. The electron configuration of a neutral zinc atom is "1s"^2"2s"^2"2p"^6"3s"^2"3p"^6"3d"^10"4s"^2".
