Calcium and barium metals due to their reactivity towards oxygen and nitrogen at elevated temperature have often being used to remove last traces of air from vacuum tubes. Heating alkaline-earth metals in sealed glass vessels under a vacuum in the presence of a desired ligand alone or with a low-melting flux agent (e.g., 1,3,5-(t-Bu) 3 C 6 H 3, 1,2,4,5-Me 4 C 6 H 2) can generate base-free complexes. Ore compounds containing beryllium, aluminum and silicon can form green and bluish-colored gemstones such as emeralds, aquamarine and alexandrite. Beryllium metal is also used to make X-ray tube windows. Barium is also an ingredient in paint pigments. Magnesium burns so actively in air, for example, that it is often used in flares because of the brilliant white light it produces during combustion. English chemist Sir Humphry Davy was the first to isolate many of the alkaline earth metals including calcium, strontium, magnesium, and barium. 5.2 Alkali metals: The word “alkali” is derived from the word al-qalÄ«y meaning the plant ashes, referring to the original source of alkaline substances.
