1. Physical and chemical properties of boron
Boron is a non-metallic semiconductor element with very high melting and boiling temperatures (2,300°C and 2,550°C respectively). Its chemistry is dominated by covalent compounds, and its electronic configuration is [He]2s 2 2p 1 . Its properties are intermediate between those of metals and metalloids.
Boron does not exist in its elemental state in nature and has two isotopes 10 B and 11 B. The 10 B isotope has a strong ability to capture thermal neutrons.
Boron compounds result from its very high reactivity.
With halogens, it gives trihalides (BF 3 ...
