WHich of the following elements are semiconductors?

Ge, Si, Te, Po, S, Al, Se, Ca

i believe only Ge, Si, Te, and Se are semiconductors, can someone confirm this? did i miss or over look something

To determine which elements are semiconductors from the given list (Ge, Si, Te, Po, S, Al, Se, Ca), you can consider the general properties of semiconductors.

Semiconductors are elements that have electrical conductivity between that of conductors and insulators. They exhibit intrinsic properties that allow them to conduct electricity under certain conditions.

Generally, the elements in Group 14 of the periodic table (Ge and Si) are considered semiconductors. Additionally, certain elements in Group 16 (such as Te and Se) can also exhibit semiconductor behavior.

Based on this, Ge, Si, Te, and Se are indeed considered semiconductors.

To confirm your answer, you can consult reliable resources such as scientific literature or reputable educational websites that provide information on the properties of elements.
