Week 5- Neon..a cool inert gas

Neon, Ne, has 10 electrons, making it's outer shell full and naming it a stable, inert gas. This is one of two true elemental inert gases, along with Helium. This element was discovered in the late 1800's by Sir William Ramsey. By 1923, Georges Claude discovered and made the first neon signs by sending an electrical discharge through neon in a sealed tube. By bending the tube, he found many more colors and neon signs soon became very popular.
