This element can be extracted from its pollucite ore by dissolving it in hydrochloric acid, after which it is sold as an azide due to its reactivity. This metal's chloride is often added to a DNA solution to achieve a gradient in isopycnic centrifugation. Robert Bunsen and Gustav Kirchhoff named this element after the blue emission lines in its spectrum. Of the non-radioactive elements, this element's 133 isotope has the lowest electronegativity and the largest atomic radius. The oscillations of this element between two ground states is the basis for the SI unit of time and for atomic clocks. For 10 points, identify this alkali metal which reacts even more explosively with water than rubidium.
