this is due to a reason that electronic configuration of elements vary from one element to other but in case of groups it remains constant
The oxidation number is the charge that an atom has when forming a compound, determined by the electron gain or loss. Valence electrons are the electrons in the outermost shell of an atom, which are involved in forming chemical bonds. While the oxidation number can vary based on the compound, the number of valence electrons remains constant for elements in the same group of the periodic table.
Because within a group, the elements all have the same number of valence electrons, so their "combining power" (oxidation number) is relatively the same. In a period, the number of valence electrons increases going left to right, so the "combining power" changes.
Group 1 elements have an oxidation number of +1.
Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).

A constant group is a term often used in social psychology to refer to a group of individuals that remains stable and unchanging over time. This can be important in research to ensure consistency in study participants. Constant groups can provide valuable insights into how individuals interact within a stable social context.

CH3CHOHCH2CH3 undergoes oxidation to form CH3COCH2CH3 (acetone). The alcohol group in the original molecule is converted into a ketone group during oxidation.
The oxidation numbers for elements in Group 1A (alkali metals) are typically +1. For elements in Group 2A (alkaline earth metals), the oxidation number is typically +2.
Elements with fixed oxidation numbers include alkali metals (group 1 elements) which have a +1 oxidation state, alkaline earth metals (group 2 elements) which have a +2 oxidation state, and nonmetals in group 17 (halogens) which have a -1 oxidation state in compounds.
No, the addition of a phosphate group is not called oxidation. Oxidation involves the loss of electrons by a molecule, while adding a phosphate group is a form of phosphorylation, which involves attaching a phosphate group to another molecule.
The oxidation numbers in group A elements typically increase by one as you move from left to right across the periodic table. For example, group 1 elements usually have an oxidation state of +1, while group 7 elements typically have an oxidation state of -1.
Elements that have a single oxidation number include group 1 elements (e.g. sodium, potassium) which have an oxidation number of +1, and group 2 elements (e.g. magnesium, calcium) which have an oxidation number of +2.
