Alkali metal - Wikipedia

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.

The solution is reacidified and sulfate is precipitated by adding BaCl 2. BaSO 4 is then collected by filtration and analyzed for d 34 S. Sulfate can also be analyzed for d 18 O in some laboratories. Large quantities of sulfate can also be analyzed for 35 S, a natural radioisotope with a half-life of 87 days, using liquid scintillation counting.
