How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors? a. They have one or two valence electrons, so they cannot lose electrons easily.

b. They have one or two valence electrons, so they can lose or gain electrons.

c. They have three to six valence electrons, so they cannot lose electrons easily.

d. They have three to six valence electrons, so they can lose or gain electrons
