How Does Excitation and Ionisation Work?

Imagine you're on a playground swing, when someone pushes you, you go higher and faster. That’s like excitation and ionisation in action!

What is Excitation?

Think of an atom as a kid on a swing. When it gets pushed (by energy), it starts swinging higher and faster, this is called excitation. The atom becomes more active, just like the kid who's now ready to jump off the swing.

What is Ionisation?

Now imagine that same kid gets pushed really hard, so hard that they fly off the swing completely! That’s ionisation. The atom loses an electron and becomes a charged particle called an ion, just like the kid who’s now floating in mid-air, no longer on the swing.

Sometimes, atoms get excited but don’t go all the way to being ions, it's like getting pushed high but still holding onto the swing. But if they're pushed just right, they might even give off light, like a neon sign glowing! Imagine you're on a playground swing, when someone pushes you, you go higher and faster.

  1. A light bulb turns on when electrons jump to a higher energy level in the filament.
  2. When you rub a balloon on your hair, it becomes charged due to ionisation.
  3. Fluorescent lights use excitation and ionisation to create bright colors.
