Did You Know?
True Identity Reveal: Neon is one of the "noble gases," meaning it's super chill and rarely reacts with other elements. It's too cool for school!
Cosmic Sparkle: Believe it or not, neon is the fifth most abundant element in the universe! We just don't have much of it here on Earth.
Earth's Elusive Gem: On Earth, neon is incredibly rare, making up only about 0.0018% of our atmosphere. It's like finding a tiny, glowing needle in a massive haystack!
How It Gets Its Glow: When electricity zips through neon gas, it excites the atoms, making their electrons jump to higher energy levels. When they fall back down, *boom* – light!
