Boron – Simple English Wikipedia, the free encyclopedia

Basic Information about Boron
– Chemical element with symbol B
– Atomic number 5
– Metalloid with properties of both metals and non-metals
– Found in chemical compounds in its ore borax
– Never found free in nature

Allotropes of Boron
– Two types of boron: amorphous and metallic (crystalline)
– Amorphous boron is a brown powder
– Metallic boron is black, hard, and a weak conductor at room temperature
– Boron is the 5th element in the periodic table
