Neon
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Neon is a gas. It is chemical element 10 on the periodic table. Its symbol is Ne.
Neon does not react with other elements, so it is found by itself. There is not much neon in the air, and it is clear, so we do not see it.
Neon gas is used in lamps. When electricity goes through the neon, it lights up in many different colors. That is why neon is used in signs.
