Oxidation number is the same as saying ionic charge. What are the oxidation numbers for thefollowing groups?Alkali MetalsHalogensNoble GasestoBoron FamilyAlkali Earth Metals

The oxidation state of an element depends on the electronic configuration of the element. So first of all we write the electronic configuration of the given groups.Groups electronic configuration of the elements detailed explanation about the electronic configuration of the group Alkali metals Only one electron present in the valance shell hence this electron is donated by the alkali metals to show the +1 oxidation state. Halogens only one electron short from the fulfilled valance shell, hence the oxidation number of the halogen is -1. Nobel gas The valance shell is completely filled, hence the general oxidation number is zero for the noble gas. Boron family Only three electrons present in the valance shell hence this electron is donated by the boron family to show the +3 oxidation state. Alkali earth metals Only two electrons present in the valance shell hence this electron is donated by the alkaline earth metals to show the +2 oxidation state.The oxidation number of the given groups are as follows: Groups Oxidation number Alkali metals +1 Halogens -1 Nobel gas 0 Boron family +3 Alkali earth metals +2
