Across
  1. 3. I am a hydrogen containing compound of Boron and I exist as a dimer
  2. 4. I am also called Sodium Tetraborate
  3. 6. My formula is Na2B4O7.4H2O
  4. 9. Boron is second most tough material after me
  5. 10. I am called the Inorganic benzene
  6. 11. My ionization enthalpy is just 1KJ per mole less than Gallium
  7. 13. We are heat resistant pyrex glass
  8. 16. My chemical formula is Ca2B6O11
  9. 17. I am found in the mineral Germanite. My abundance is just 0.1% to 1%
  10. 19. I am the colour of Nickel metaborate
