Chapter 11: Introduction to Modern Atomic Theory

White light, light from the sun, produces a continuous emission spectrum containing ALL colors in the visible region.

If a hydrogen atom contains a proton (in the nucleus) and an electron, how is it that the electron and proton can remain 'stable'?

Why doesn't the electron spiral down into the nucleus? Electrons do not spiral into the nucleus, so how does the electron exist in an atom?

Why does the emission spectrum for a hydrogen atom in the visible region of the electromagnetic spectrum contain a few discrete lines?

Emission spectra of other elements also show lines. Why do we only see lines when we view the light given off by an element that has been heated?
