Give reasons for these:(i) Inert nature of Hydrogen at room temperatur

1.	Give reasons for these:(i) Inert nature of Hydrogen at room temperature (ii) Oxy- Hydrogen torch is used for cutting & welding purpose (iii) LiH is least ionic among Alkali Metal Hydrides.
Answer» (i) High bond dissociation energy of H-H bond (ii) Hydrogen molecule dissociate into atomic hydrogen at very high temperature (4000K) (iii) Because of least electronegativity difference.
