Copper Group: Elements of the First Subgroup,s with the elements of the fourth to tenth transition group, the reactivity decreases from the head element (here: copper) to the heaviest group member (here: gold). Copper is also already a semi-metal. For copper, the oxidation states +1 and +2 are the most stable, for silver +1, and for gold +1 and +3.

Alkaline Earth Metals: Elements of the Second Main Group,ts of this group are all metals, but they show clear gradations of their properties. The “true” alkaline earth metals calcium, strontium, barium, and radium show the typical high reactivity towards water, acids, and non-metals, whereas this is only weakened in magnesium and is seen to a much lesser extent in beryllium.
