What is Alkaline earth metal?
[[File:Erdalkali.jpg|thumb|The alkaline earth metals in a row]] The '''alkaline earth metals''' are the second group of metals on the [[periodic table]]. They are related to the [[Alkali metal]]s, but they do not react as much because they need more [[energy]] to remove their two [[electron]]s, so they do not have to be stored in petrol.As [[ion]]s they have a [[Electric charge|charge]] of +2a. The alkaline earth metals are mostly silver colored, soft metals, which react readily with ''halogens'' and water to form salts, though not as rapidly as some of the alkali metals, to form'' alkaline hydroxides''. Many ''prokatates and hantates'' can be found in the crust of these metals The alkaline earth metals are: [[Beryllium]] (Be), [[Magnesium]] (Mg), [[Calcium]] (Ca), [[Strontium]] (Sr), [[Barium]] (Ba), and [[radium]] (Ra). Beryllium is very brittle metal that is used in gemstones. Magnesium is used in making steel alloys. Calcium can be used in dairy products like milk. Strontium is used for making glass for TVs and to make fireworks red. Barium is used in fireworks to turn them green. Radium is a very [[radioactive]] metal used in glowing watches. {{Periodic Table}} {{wiktionary}} {{chem-stub}} {{authority control}} [[Category:Alkaline earth metals]]
