Valency is zero, being a noble gas, does not react because of that fact.
valency of argon is 0 that the shell is completely filled
Neon (Ne) is a noble gas and has a valency of 0. It is stable with a full outer shell of electrons.
Neon has a complete outer electron shell with 8 electrons, making it stable and unreactive. Since it does not need to gain, lose, or share electrons to achieve a stable electron configuration, it is considered to have zero valency.
Phosphorus has a valency of 3 because it has 5 valence electrons in its outer shell. By sharing/gaining/losing 3 electrons, it can achieve a stable electron configuration similar to the noble gas neon. This results in a valency of 3 in chemical reactions.
Noble gases such as helium, neon, argon etc have completely filled valence orbitals, and hence have sable electronic configuration. They do not form bond with other elements. In other words, they are chemically inert and have zero valency.

The valency of lithium is 1. It has one valence electron in its outer shell.
Helium, neon, and argon have a zero valency because they have a full outer electron shell (valence shell). This makes them stable and unreactive because they do not need to gain, lose, or share electrons to achieve a full valence shell. Since they already have a complete set of electrons, they do not form chemical bonds easily.
the valency is 4
Its valency is 0.
the valency for nitrite is 5
magnesium has a valency of 2
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
