Strontium - Wikipedia
Strontium is intermediate between calcium and barium in its reactivity toward water, with which it reacts on contact to produce strontium hydroxide and hydrogen gas. Strontium metal burns in air to produce both strontium oxide and strontium nitride , but since it does not react with nitrogen below 380 °C, at room temperature, it forms only the oxide spontaneously.

Calcium: The mineralogy of Calcium
Geochemistry of Calcium Goldschmidt classifiion: Lithophile Ca 2+ was one of the ions least depleted from the mantle in the formation of the crust. Ca 2+ is enriched in Ca-Al-rich inclusions in meteorites relative to the composition of the solar system. Ca 2+ enters early-forming phases in igneous rocks.

Which is more reactive, beryllium, magnesium, or …
Well, if you check the reactivity series, calcium is more reactive than magnesium. This means there''s a a trend of increasing reactivity as we go down the group. As beryllium is above magnesium, it must be the least reactive. Then magnesium is in
Barium | Ba - PubChem
Barium is a naturally occurring alkaline metalloid element with atomic syol Ba, atomic nuer 56, and atomic weight 137 that is only found in coination with other elements, typically barite (barium sulfate) and witherite (barium carbonate), or chemicals. Barium is used in many industrial processes, as well as in diagnostic testing, fireworks, and pesticides.

Barium : definition of Barium and synonyms of Barium …
Barium is chemically similar to magnesium, calcium, and strontium, being even more reactive. It always shows the oxidation state of +2. [ 1 ] Reactions with chalcogens are highly exothermic (release energy); the reaction with oxygen (and thus the air) occurs at room temperature, thus bearing the need to hide barium from it under oils or inert gases.
