We know neon mostly by their color and their brightness shown in the signs we see at night. Electricity flowing through the signs causes it to glow up.

Neons have 10 protons, 10 electrons, and most likely 20 neutrans with two energy levels (shown on the picture above). The first energy level, as the picture shows, has two electrons and the second energy level contains eight.

Neons are colorless and odorless, as said in the profile. Then why does it have such a variety of colors? Neons, mixed with other compounds will produce NEON COLORS.
