(d) 18

The number of valence electrons in Cl ion is 8. Valence electrons is the total number of electrons that make up an atom’s outermost shell known as the valence electron.

Valence Electrons in Cl ion

The number of electrons an atom loses, gains, or shares with other atoms in order to achieve a stable configuration is known as its valency.

For example:

Atomic Configuration of Carbon (C ) is ( 6 ) = 2,4

  • Carbon will have a valency of 4, as it requires an additional 4 electrons to achieve a stable state.
  • Since carbon has four electrons in its outermost shell, it also has four valence electrons.

Atomic Configuration of Nitrogen N ( 7 ) = 2,5

The valency of nitrogen is three because it needs three more electrons to complete its octet, but nitrogen only has five valence electrons. If an atom receives electrons, it becomes a negatively charged ion (cation), but if it loses them, it becomes a positively charged ion (cation) (anion).

Here the number of Cl (2,8,7) = Valence electron 7

Now, Cl= (2,8,8) = Valence electron 8


Number of valence electrons in Cl- ion are (a) 16 (b) 8 (c) 17 (d) 18

In Cl ion, the number of valence electrons is 8. The total number of electrons that makes up the outermost cell is the valence electrons. Valency is defined as the number of electrons gained or lost in order to achieve a stable configuration.
