leelismuldmetallide
Leelismuldmetallide, also known as alkaline earth metals, are a group of six chemical elements that form group 2 of the periodic table. These elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are characterized by having two valence electrons in their outermost electron shell, which they readily lose to form positive ions with a +2 charge.
In their elemental form, leelismuldmetallide are reactive metals. They are soft, silvery-white, and have relatively low
Leelismuldmetallide compounds are abundant in the Earth's crust. Calcium is particularly common, forming minerals like limestone,
Due to their reactivity, leelismuldmetallide are not typically found in their pure metallic state in nature.
