We are told that the noble gases, with their atomic numbers, are: helium 2, neon 10, argon 18, krypton 36, xenon 54, radon 86, and ununoctium 118.Thus, the sizes (number of elements) of the rings of electrons around the nucleus are the differences between the atomic numbers: 2, 8,...
atomic number 2,He,helium- a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas) ...

The noble gases are relatively nonreactive. This is because they have a complete valence shell. They have little tendency to gain or lose electrons. The noble gases have high ionization energies and negligible electronegativities. The noble gases have low boiling points and are all gases at room...

These electrons combine with other atoms to form molecules. Inert gases have 2 or 8 electrons in the outermost orbital due to which their valency is zero.Helium: Having atomic number 2, helium is the second most abundant element in the universe after hydrogen (H). It is mainly used for ...
We know that atoms react with each other to gain full outer shells of electrons. Since the atoms of noble gases have full shells already, they have no need to react. The full shells make them stable. What are the uses of the noble gases?
The atomic number of Helium is 2 1s2 The outer most shell of He is complete and they are happy... Learn more about this topic: Noble Gases on the Periodic Table | Group 8A Elements from Chapter 7/ Lesson 9 54K In this lesson: understand what the noble gas elements are, where they...
