Question

materials.
Germenium and silicon are called semico
-ductors. Why?​

Answer 1

Explanation:

Since they are in the same column, we know that silicon and germanium have the same number of electrons in their outer or valence shell. Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell.

Answer 2

Answer:

Silicon and germanium are called semiconductors because they have 4 valence electrons in their outermost shell which gives them the ability to gain or lose electrons equally at the same time
