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

Here, we are required to identify how the number of Valence electrons on atoms of metalloids explain why metalloids are semiconductors.

  • This is because; They have three to six valence electrons, so they can lose or gain electrons

Metalloids are elements in the periodic table which are characterized by the the presence of 3 to 6 Valence electrons.

  • Metalloids unlike Alkali and alkali earth metals (which have 1 and 2 Valence electrons and are highly electropositive) and halogens( with valency of 7 and are highly electronegative) have three to six valence electrons and are therefore able to lose or accept electrons.

Ultimately, the presence of three to six Valence electrons and the ability to either lose or gain electrons is the criteria for their semiconductor character.
