Alkaline earth metal
An alkaline earth metal is an element from group 2 of the periodic table, that is, one of beryllium, magnesium, calcium, strontium, barium or radium.[1] The name has been in use since the early nineteenth century, and connects the metals with their oxides and hydroxides (the "alkaline earths"),[2] less soluble in water than the "alkalis proper" (such as caustic soda) but still giving distinctly alkaline solutions.
