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.
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.
The oxidation number for group 2 elements is typically +2. These elements have 2 valence electrons that they can lose to form a 2+ cation.
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.
In group 2 elements like alkaline earth metals, the common oxidation number is +2, not -1. This is because these elements tend to lose 2 electrons to achieve a stable octet configuration and form 2+ cations.

The oxidation number for group 2 elements is typically +2. These elements have 2 valence electrons that they can lose to form a 2+ cation.
Elements in group 2 mostly takes the oxidation number +II.
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.
In group 2 elements like alkaline earth metals, the common oxidation number is +2, not -1. This is because these elements tend to lose 2 electrons to achieve a stable octet configuration and form 2+ cations.
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.
In the carbon group (Group 14), the elements have oxidation numbers of +4 for carbon, +2 or +4 for silicon, +2 or +4 for germanium, +2 or +4 for tin, and +2 or +4 for lead. The oxidation number can vary depending on the specific compound or ion that the element is part of.
Elements in group 2 have an oxidation number of +2 because they readily lose two electrons to achieve a full outer shell, which is the most stable electron configuration. This results in a +2 oxidation state as they become positively charged cations.
Group 1 elements (alkali metals) typically have an oxidation number of +1. Group 2 elements (alkaline earth metals) typically have an oxidation number of +2. Group 3-12 elements (transition metals) can have varying oxidation numbers depending on the compound they are in.
Because there in group 2
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
