Solution: Which species is diamagnetic? Cr2+, Zn, Mn, C

Problem

Which species is diamagnetic? Cr2+, Zn, Mn, C

Solution
  • Diamagnetic species are atoms that has zero unpaired electrons. We can determine this by setting up the orbital diagrams of the valence electrons for each atom.

  • Writing the electron configurations will help us identify the valence electrons. Recall that s, p, d and f blocks in the periodic table which can help us 

  • For Cr2+, find the electron configuration of the neutral Cr first
