Within a group they have properties that are very similar, while within a given period they can behave chemically extremely differently.

Main group: it consists of the alkali metals sodium, lithium, potassium, francium, rubidium and cesium. Hydrogen is not included.
Main group: with the alkaline earth metals calcium, magnesium, beryllium, barium, radium and strontium.
Main group: the aluminum-boron group.
