WebBoron is a chemical element with the symbol B and atomic number 5. It is a metalloid, meaning that it exhibits some properties of both metals and nonmetals. It is a hard, black, brittle solid that is highly chemically reactive. Boron is not found in its elemental form in nature, but it is present in a variety of minerals and compounds. WebBoron is a trace element that is naturally present in many foods and available as a dietary supplement. It is a structural component of plant cell walls and is required for plant growth, pollination, and seed formation [ 1 ].
