This sentiment was echoed by Morris Travers, with whom Ramsay co-discovered the four noble gases—neon, argon, krypton, and ...

Neon lights rely on neon gas and other noble gases to emit light, while fluorescent lights use a phosphor coating inside the tube to produce their high-intensity glow. This is why fluorescent ...

Xenon's discovery concluded an intense period of research on noble gases. Much heavier than neon and krypton, it had not been explicitly predicted, and was sufficiently rare to avoid chance detection.

A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of ...
