noun / adjective
neon
NEE-ahn/ˈniːɑːn/
A colorless gaseous element used in electric lighting.
Electricity makes neon glow orange-red inside the transparent discharge tube.
Etymology
Greek neos, “new,” supplied the name because the element was newly discovered. Its ability to emit colored light when electrified in a sealed glass tube led to its use in bright advertising signs.
In context
neon is also a pure element because we don't have two different elements there's only just one neon
