The chemical inertness of certain gases is subtler to explain. Generally speaking, when two atoms come into proximity, the highest energy, or valence, orbitals of the atoms change substantially and the electrons on the two atoms reorganize. If this reorganization lowers the total energy of the electrons involved, a chemical bond can form. For ordinary, non-inert atoms, the electrons are relatively pliable and bonds often form. The electrons in inert gases, however, are relatively resistant to this proximity effect, so these gases very rarely bond to form molecules.
For over one hundred years neon signs have been helping businesses draw in customers with their alluring gaseous displays. Cities such as Manhattan and Las Vegas have long been popular travel destinations due to their vintage neon signs. Here are some of the reasons why you should consider a stock neon sign for your business
