Group 2 (IIA) consists of beryllium, magnesium, calcium, strontium, barium, and radium. This family of elements is known as the alkaline earth metals, or just the alkaline earths. Like those of the Group 1 metals, the oxides of the alkaline earths can...

On the Periodic table, Group 2 (IIA) consists of beryllium, magnesium, calcium, strontium, barium, and radium. This family of elements is known as the alkaline earth metals, or just the alkaline earths. Although early chemists gave the name...

A method for removing sulfur dioxide from combustion stack gas. A slurry of finely ground alkaline material such as calcium carbonate is sprayed into the effluent gases before it enters the smokestack. The material reacts chemically with sulfur dioxide...

Any of the six chemical elements in the second leftmost group of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium). Their name harks back to medieval alchemy. Their atoms have two electrons in the outermost shell, so...

The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). The alkaline earth metals provide a good example of...
