Electronegativity is a measurement of the power of an atom to attract electrons. The Noble gases, like helium, neon, and argon all have full valence shells. This means they are very stable and have no need to bond.
There are several methods of calculating electronegativity, and some of those methods do give values for the Noble gases. However, these numbers are not generally meaningful since the noble gases do not have a measurable electron affinity. Several of the noble gases can form bonds under special curcumstances.
Helium and neon are odd elements because they have an odd number of protons in their nucleus. Hydrogen and argon are even elements because they have an even number of protons.
Helium and neon are in the same group, Group 18 (Noble Gases), also known as Group 8A. Argon is also in Group 18.
Among neon, argon, and helium, neon is the most reactive because it tends to form compounds with other elements under extreme conditions. Helium and argon are noble gases and are generally unreactive due to their stable electronic configurations.
The element that forms compounds with all other elements except helium, neon, and argon is fluorine. Fluorine is a highly reactive nonmetal that readily forms compounds with most elements due to its strong electronegativity.
Neon belongs to group of noble gases. The other elements are Helium, Argon, Krypton, Xenon and Redon.
Helium, neon, and argon are the three lightest members of the noble gases.
The first four are (in order of increasing number / mass: He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton Xe = Xenon and Ra = Radon are the other two noble gases

Helium, argon, and neon are noble gases with different atomic numbers: helium (2), neon (10), and argon (18). They vary in terms of their densities, boiling points, and chemical reactivity. Neon has the lowest boiling point and argon has the highest atomic weight among the three.
Noble gases
Elements
They are all gases.
Helium Neon and Argon The noble gas group contain: helium, neon, argon, krypton, xenon, radon, ununoctium.
Helium and neon do not typically react with iron under normal conditions. Argon is inert and does not chemically react with iron.
Helium and neon are odd elements because they have an odd number of protons in their nucleus. Hydrogen and argon are even elements because they have an even number of protons.
The noble gases group on the periodic table includes helium, neon, argon, krypton, xenon, and radon. These elements are known for their stable and unreactive nature due to having a full outer electron shell.
