If An Element Has An Odd Number Of Electrons Then It Is Paramagnetic.

If An Element Has An Odd Number Of Electrons Then It Is Paramagnetic.

• A. Odd
• B. Even
• C. Both Odd And Even
• D. Cannot Be Determined

Answer: (A)

Paramagnetism comes from unpaired electrons. In atoms, electrons fill orbitals two at a time with opposite spins. If the total number of electrons is odd, you can’t pair them all; at least one electron remains unpaired. That unpaired electron provides a magnetic moment that aligns with an external magnetic field, making the species paramagnetic. So an element with an odd number of electrons necessarily has unpaired electrons and is paramagnetic. (Even-numbered systems can be fully paired and diamagnetic, though there are exceptions in some molecular cases.)
