Why Boron is a Metalloid?
- Their characteristics fall between those of non-metals and metals.
- Examples include germanium, boron, silicon, tellurium, polonium, arsenic, and tellurium.
- Metalloid with a small atomic size, boron.
- By exchanging valence electrons with the nearby elements, it creates covalent bonds with them.
- Because covalent bonds are strong and require a lot of energy to dissolve, they have a higher melting point than metalloids.
