What are the properties of semi - metals?
1. Semi-metals, also known as metalloids, have properties that are intermediate between metals and non-metals.
2. They typically have physical properties such as metallic luster and conductivity of electricity, but lack the malleability and ductility of metals.
3. Semi-metals have a mixed bonding character of metallic and covalent bonds, giving them unique chemical properties.
4. They are typically brittle solids with high melting points and boiling points.
5. Semi-metals can exhibit both metallic and non-metallic properties depending on the specific conditions, such as temperature or pressure.
6. They are commonly used in semiconductor materials and have applications in electronics, optoelectronics, and solar energy technologies.
