The valency of sodium is

Content Curator

The valency of sodium (Na) is 1.

Valency refers to the ability of an element to form chemical bonds with other elements. It is determined by the number of electrons in the outermost shell (valence shell) of an atom.

In the case of sodium, it has an electron configuration of [Ne] 3s¹, where [Ne] represents the electron configuration of a neutral neon atom. Sodium has only one electron in its valence shell, which means it can form one chemical bond with another element.

To calculate the valency of an element, you can use the following steps:

Determine the electron configuration of the element: In this case, the electron configuration of sodium is [Ne] 3s¹.
Count the number of electrons in the valence shell: The valence shell of sodium is the 3s orbital, which has only one electron.
The valency of an element is equal to the number of electrons in the valence shell that are available for bonding. In the case of sodium, its valency is 1.

So, the valency of sodium (Na) is 1.
