The substance that has little or no band gap is to be identified. Concept Introduction: The energy levels in molecules/atoms are known as energy bands. These bands are of two types which are given as, Valence band. Conduction band. In substances the conductivity depends upon the number of valence electrons. Valence band comprises of valence electrons and has lower energy. Conduction band has higher energy. The difference between these bands is known as band gap. In metals, the band gap is always negligible or zero. In non-metals, the band gap is extremely high. To determine: The correct option corresponds to the little or no band gap. Correct answer: The correct option is (a).
