What do metal and metalloids have in common?

Metalloids are similar to metals in that they both have valence orbitals that are highly delocalized over macroscopic volumes, which generally allows them to be electrical conductors.

What is the property of metalloids that is similar to that of metals?

Metalloids tend to be shiny like metals but brittle like nonmetals. Because they are brittle, they may chip like glass or crumble to a powder if struck. Other physical properties of metalloids are more variable, including their boiling and melting points, although all metalloids exist as solids at room temperature.
