The number of valence electrons in a semiconductor element is 4. In such a case, the elements will possess properties in between metallic and nonmetallic elements. The elements or material will not be able to conduct electric current as efficiently as a conductor and at the same time.

Answer: A semiconductor has four electrons in its valency ring.

A semiconductor material having four valence electrons cannot block the flow of current through them. The conductivity of such elements is moderate which is not good as well as not bad. Some examples of such materials are carbon, silicon, and germanium.

Electrical Conductivity and Valence Electrons

The elements are divided into three groups based on their electrical conductivity. They are conductors, semiconductors, and insulators. Some information on conductors and insulators are given below:

  • Conductors: They are the materials such as metallic substances that are the good conductor of electricity. The valence electrons in these materials are less than 4. The most common metallic materials used for electrical conductivity are aluminium, magnesium, copper, etc.
  • Insulators: The materials in which the number of valence electrons in the atom is more than four and the element behaves as a non-metal is called an insulator. Such materials are bad conductors of electricity. Some examples of insulators are nitrogen, neon, and sulphur.


A semiconductor has ______ electrons in its valency ring.

There are four valence electrons in the valency ring of a semiconductor. For example – carbon, silicon, and germanium.
