Introduction to Group 2

Trends in Group 2 elements

The elements in Group 2 of the periodic table (Beryllium to Barium) are known as the Alkaline Earth Metals. Every Group 2 atom has two outer electrons in an sss subshell. During reactions, they lose these two electrons to form 2+2+2+ ions, behaving as reducing agents.
