What are atoms that have less than four valence electrons?

What are atoms that have less than four valence electrons? Correct Answer conductor

Based on electrical conductivity, the elements are divided into three groups:

Conductors:

All metallic substances are a good conductor of electricity. it has less than 4 electrons in its outermost shell that means it has less than four valence electrons.

Semiconductors:

Semiconductors are materials that have a conductivity between conductors (generally metals) and non-conductors or insulators. It has 4 valance electrons in the outermost shell.

Insulators:

When the number of valence electrons in the atom is more than four, the element behaves as non-metal. The non-metal is a bad conductor of electricity.

Which of the following statements is/are correct? 1) Conductor contains a large number of electrons in the conduction band at room temperature. No energy gaps exist and the valence and conduction bands overlap. 2) A semiconductor is a material in which the energy gap is so large that practically no electron can be given enough energy to jump this gap. 3) An insulator is a solid with an energy gap small enough for electrons to cross rather easily from the valence band to conduction band.
