When Mendeleev designed his periodic table, he arranged the elements according to their similarities in physical and chemical properties. He placed lithium (Li), sodium (Na), and potassium (K) in the first column - the alkali metal family. He placed magnesium (Mg) and Calcium (Ca) in the second column - the alkaline earth metal family. It is now your turn to determine why Mendeleev grouped these elements together. What common behaviour do they exhibit? Why are they placed in that particular sequence?
