Group 1 (with one valence electron) and Group 2 (with two valence electrons) are called thealkali metalsand thealkaline-earth metals, respectively. Two series of elements branch off from Group 3, which contains thetransition elements, or transition metals; elements 57 to 71 are called thelantha...

Alkaline earth metals are elements that belong under group II of the periodic table having valence electrons at the s-orbital of the element. Because alkaline earth metals have two electrons more than the nearest noble gas configuration of the previous period, the ions they form ...

Not altogether surprisingly, the currently popular medium-long form seems to strike a compromise between displaying too many chemical similarities while at the same time maintaining much overall regularity, although not going so far as to place the element helium in the alkaline earth group.

Alkaline Earth Metals Group 2 elements, reactive with two valence electrons. Transition Metals Groups 3-12, characterized by partially filled d-orbitals. Halogens Group 17 elements, very reactive non-metals with seven valence electrons. Noble Gases Group 18 elements, inert due to full valence shell...
