2019-4-25 · Yet another similarity the alkaline earth metals have with the alkali metals is the fact that four of the them — magnesium, calcium, strontium, and barium — were either identified or isolated in the first decade of the nineteenth century by English chemist Sir Humphry Davy (1778-1829). Around the same time, Davy also isolated sodium and potassium from the alkali metal family.
