Why do we analyse Barium?

Barium, like all the other alkaline earth metals, is soft and silvery (however forms a very dark grey colour upon oxidation unlike most other alkaline metals), reacts with water violently and is not found in its elemental form in nature due to its high reactivity. However, it exhibits interesting properties, such as YBCO, a high-temperature superconductor which was one of

the first alloys to exhibit these properties.
