Though not part of natural gas, this  element is released during natural gas extraction, which is increasing the cost of cooling MRI scanners   due to a shortage of this element.
This element is often used in mass spectrometers to detect leaks because it is a very minor constituent   of air, it is safe, and it is easy to separate from other gases.

The fusion of three of its nuclei creates a carbon nucleus. The  name of this element arose because it was first observed in the Sun's spectrum, and its nucleus is an  alpha particle. Name this lightest noble gas, the second element on the periodic table.
