Quick notes
- Helium appears on spectroscope as a bright yellow line, corresponding with the D3 solar line. This contrasts with the argon spectrum "consisting of lines more or less evenly distributed across the whole field of the instrument." Helium found while looking for argon after its discovery in 1894.
- Besides diffusely in the atmosphere, small amounts of helium are found in mineral springs (especially Bath in England) and within certain minerals. Helium sometimes accompanies argon and nitrogen.
- Also found in natural gas in Kansas.
- Helium can be cooled and liquified; this was first done by Prof. Heike Kamerlingh Onnes of Leiden.
