What Are the Alkaline Earth Metals?
Alkaline earth metal refers to group IIA elements in the periodic table of elements, including beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), radium (Ra), and six elements. Among them, beryllium is also a light rare metal, and radium is a radioactive element. The alkaline earth metal covalent electron configuration is ns 2 . In the chemical reaction, electrons are easily lost, +2 valent cations are formed, and strong reducing properties are exhibited. Calcium, magnesium, and barium are abundant in the earth's crust, and their simple substances and compounds are widely used.
