A periodic table element box for neon displays its atomic number 10, symbol Ne, atomic weight 20.1797, electron configuration, and labels indicating it is a noble gas, a gas at room temperature, and has a face-centered cubic crystal structure.

Crowds of people walk past brightly lit neon signs for bars and music venues on Lower Broadway in Nashville at night.
