What are Rare Earth Metals?

Rare earth elements include Scandium (Sc), Yttrium (Y), and the 15 Lanthanides (La–Lu). These elements are known for their:

  • Unpaired electrons (f-orbitals)
  • High magnetic susceptibility
  • Optical and catalytic activity
    These unique properties make them indispensable in quantum computing, green energy tech, and photonics.
