Answer to Question #84624 in General Chemistry for Jitesh mandloi

Question

Boron is non reactive in non temprature why???

Answer 1

Crystal Boron consists of icosahedra (specific structure) and the energy of bonds B – B between icosahedra is very high (243 kJ/mole) which determines high solidity, high temperatures and energies of phase transition and chemical inertness (non reactive).
