- Boron is the only metalloid in Group 13 of the periodic table.
- Group 13 elements are also known as the boron group, which includes boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
- Among these elements, boron exhibits properties of both metals and non-metals, classifying it as a metalloid.
- Metalloids have intermediate properties and are often semiconductors, which boron also exhibits.
- Boron is essential for plant growth and has various industrial applications, including in borosilicate glass and detergents.
Additional Information
- Group 13 elements typically have three electrons in their outermost shell, leading to a +3 oxidation state in compounds.
- Boron compounds, such as borates, are used in glassmaking, ceramics, and as a mild antiseptic.
- Boron is also a component of boron nitride, a material with properties similar to carbon-based materials like graphite and diamond.
- In the periodic table, boron is located in period 2, making it the lightest element in Group 13.
- The unique properties of boron, such as its high melting point and hardness, make it useful in various high-temperature and abrasive environments.
