I have an assignment to 'Research ionization energy levels and come up with 3 real world applications'. I'm not so sure how to do this. Any help would be appreciated.

Answer 1

Look up Lasers
Look up plasma arcs
Look up neon lights

Answer 2

Do these three things have ionization energy levels? To be honest, I'm not quite sure how ionization works.

Answer 3

Answer 4

I'm still having a little trouble. Is there any way you can explain the connection between lasers, plasma arcs and neon lights?
