A key tool in atomic physics is the hydrogen spectrum, which shows the quantised energy levels of the electrons in a hydrogen atom. The electrons in hydrogen gas absorb energy and travel to higher energy levels when the gas is excited,...

The light spectrum is the collection of colours that are generated when light is dispersed through a medium, such as a prism. This dispersion reveals the various wavelengths of visible light, with each wavelength corresponding...

This video covers:

- What flame emission spectroscopy (also called flame photometry
) is.
- How it can be used to identify the metal ions present in
a sample
- How it shows the concentration of each metal ion...
