HI

⭐️ BORON ⭐️

❇️ Physical Properties:-

⏺️Boron is allotropic and exists as a powder or a metal-like substance.

⏺️Its colour ranges from a dark brown to black powder or a jet-black to silver-gray metal-like element.

⏺️Its crystalline form is very hard, lustrous, but brittle.

⏺️All forms of boron have very high melting points.

⏺️Boron is a good electrical conductor at high temperatures and a poor conductor at low temperatures.

❇️ Chemical Properties:-

⏺️The chemical reactivity of boron depends on its form.

⏺️The crystalline form is far less reactive than the powder form.

⏺️The powder is oxidised slowly in air at room temperature and ignites spontaneously at high temperatures to form an oxide.

⏺️The crystalline form is oxidised only very slowly, even at higher temperatures.

⏺️Boron forms compounds with oxygen, hydrogen, the halogens, nitrogen, phosphorus, and carbon.
