Alkaline earth metals
“What do Chemists mean when they talk about the Alkaline earth metals?”
To continue with our tour of the periodic table, a group that definitely needs attention is the alkaline earth metals. The alkaline earth metals are the second group on the left of the periodic table. The elements that make up this group include beryllium [Be], magnesium [Mg], calcium [Ca], strontium [Sr], barium [Ba], and radium [Ra]. All of these elements share many peculiar properties, such as the fact that they hold two valence electrons, silver colored and soft, have low melting points, boiling points, and densities, and all of their valence electrons are in the 2s range.
