Metalloids exhibit a combination of localized and delocalized bonding. How does this relate to the properties of metalloids?

The combination of localized and relocated connections is what allows the metalloid to be a transitional element between a metal and a non-metal. With that, it manages to be a solid and shiny element, but brittle.

Explanation:

A metalloid is also called ametal and has intermediate characteristics between metal and non-metal elements. they are characterized as solid, shiny, brittle and good idolizers of temperature and electricity, however, they assume the characteristics that metals present in relation to conductivity when they are heated. This is because the increase in temperature makes the electrons connected by weak bonds become free, making them semiconductors.
