For An Element With An Even Number Of Electrons, Its Paramagnetic Or Diamagnetic Nature Is Determined By What?

For An Element With An Even Number Of Electrons, Its Paramagnetic Or Diamagnetic Nature Is Determined By What?

• A. Electron Configuration
• B. Energy Diagram
• C. Crystal Structure
• D. Ionization Energy

Answer: (B)

Magnetic behavior comes from unpaired electrons, and the way those electrons occupy available orbitals is shown in the energy diagram. When electrons fill degenerate orbitals, Hund’s rule can leave some electrons unpaired even if the total number of electrons is even. The energy diagram directly displays which orbitals are occupied and whether spins are paired, so it tells you if there are unpaired electrons (paramagnetic) or all are paired (diamagnetic). Crystal structure and ionization energy don’t reveal this pairing information for the neutral atom, and while electron configuration relates to the same idea, the occupancy illustrated in the energy diagram is the clearest indicator in this context.
