Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Even nominally disordered (amorphous) boron contains regular boron icosahedra which are bonded randomly to each other without long-range order. Crystalline boron is a very hard, black material with a melting point of above 2000 °C. It forms four major allotropes: α-rhombohedral and β-rhomb… Webhalf-life 10 −12 seconds boron-16: ≤190 10 −9 seconds (nanoseconds) isotope half-life 10 −9 seconds lithium-12 <10 boron-18: 26 carbon-21: 30 fluorine-28: 40 oxygen-26: 40 ... half-life 10 −6 seconds lead-196m2 <1 polonium-192m ~1 radon-210m3: 1.04 thorium-219: 1.05 polonium-206m2: 1.05 radon-210m2: 1.06 curium-243m: 1.08 actinium-218 ...
