Question

which lists the elements in order from most conductive to least conductive?
potassium (k), selenium (se), germanium (ge)
germanium (ge), potassium (k), selenium (se)
selenium (se), germanium (ge), potassium (k)
potassium (k), germanium (ge), selenium (se)

Explanation:

Metals are good conductors, metalloids have intermediate conductivity, and non - metals are poor conductors. Potassium (K) is a metal, germanium (Ge) is a metalloid, and selenium (Se) is a non - metal. So, the order from most conductive to least conductive is metal > metalloid > non - metal.

Answer:

D. potassium (K), germanium (Ge), selenium (Se)
