Key Differences

Boron is a chemical element with the symbol B and atomic number 5, found naturally in the Earth's crust and in the solar system. On the other hand, borax is a compound derived from boron; its chemical name is sodium borate, and its formula is Na2B4O7·10H2O, indicating it includes boron, sodium, and water molecules.
Boron plays a critical role in plant growth and is utilized in the production of fiberglass and borosilicate glass. Borax, conversely, is used widely in various applications like detergents, cosmetics, glazes, and fire retardants, showcasing its versatility as a boron compound.
Boron is an essential human nutrient, beneficial in small amounts but harmful in large doses. Borax, while also featuring in some health supplements, can be harmful if ingested in large amounts or exposed to the skin and eyes, emphasizing the need for careful handling.
Boron is typically mined directly from the Earth as borate minerals, such as borax and kernite. Borax itself is obtained from these mined minerals through a refining process that involves repeated dissolving, filtering, and evaporation stages.
Boron appears as a brownish-black or silver-white metal, whereas borax often takes the form of colorless, white, or bluish-green crystals.
