What do we call the valence when it is filled

When the outer electron level is filled, we call it the noble gas configuration.

I am not certain what you mean by valence when it is filled.

The valence, or valence shell, is the outermost electron shell of an atom. It is involved in determining the atom's chemical properties and ability to form bonds with other atoms. When we say the valence is filled, it means that all the available spaces in the outermost shell are occupied by electrons.

To determine if the valence is filled, you need to know the electron configuration of the atom. The electron configuration describes the arrangement and distribution of electrons within the atom's orbitals or shells.

One way to determine if the valence is filled is by referring to the periodic table. The periodic table is organized in a way that groups elements with similar properties together. The group number of an element indicates the number of valence electrons it has. For example, elements in Group 1 (such as hydrogen, lithium, and sodium) have one valence electron, while elements in Group 18 (also known as the noble gases) have a completely filled valence shell.

So, when the outer electron level (valence shell) of an atom is completely filled, it is referred to as having a noble gas configuration. The noble gases (helium, neon, argon, krypton, xenon, and radon) have completely filled valence shells, making them stable and unreactive. Other elements strive to achieve the same electron configuration as noble gases by gaining, losing, or sharing electrons to fill their valence shells.
