Question

The electrons in the outermost orbit of an atom are known as:

1. strong bond electrons
2. drift electrons
3. non-conductive electrons
4. valence electrons

Answer 1

Correct Answer - Option 4 : valence electrons

Valance Electrons: A valence electron is simply the total number of electrons present in the outermost shell or orbit of an atom.

Valency: Valency is the number of electrons an atom loses, gains, or shares with other atoms in order to get a stable configuration.

• Valance electrons are responsible for the electrical conductivity of an element.
• The outermost shell for a given atom is called the valence shell.
• The valence shell of an atom can contain up to eight electrons.
• The conductivity of the atom depends on the number of electrons that are in the valence shell.
