The elements helium, copper, neon and argon are commonly referred to as noble gases. These are mainly obtained from air in an air separation unit.
Elements
Helium and neon are odd elements because they have an odd number of protons in their nucleus. Hydrogen and argon are even elements because they have an even number of protons.
