Identify the group of each element: B (Boron) is in Group 13, Ge (Germanium) is in Group 14, Te (Tellurium) is in Group 16, As (Arsenic) is in Group 15, and Cl (Chlorine) is in Group 17.
Determine which elements are metalloids: Common metalloids include B, Si, Ge, As, Sb, and Te.

Conclude that Te (Tellurium) is the element that is both a metalloid and a chalcogen.
