The oxidation number of an element is a measure of the number of electrons that an atom of that element has gained or lost to achieve a stable electron configuration. It is a value that is assigned to an element in a compound to help track the flow of electrons in chemical reactions. Oxidation numbers can be positive, negative, or zero, depending on whether the element has lost, gained, or shared electrons.
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.
Group 1 elements have an oxidation number of +1.
Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
The oxidation number for group 2 elements is +2. This is because group 2 elements have 2 valence electrons, so they tend to lose these 2 electrons to achieve a stable electron configuration.

The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
all the pure elements have zero oxidation state.....
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.

The oxidation number for group 2 elements is +2. This is because group 2 elements have 2 valence electrons, so they tend to lose these 2 electrons to achieve a stable electron configuration.
Elements in group 2 mostly takes the oxidation number +II.
No, not all elements in a group have the same oxidation numbers. The oxidation number of an element can vary depending on the compound it is a part of and the specific chemical bonds it forms. Group trends can provide some guidance on common oxidation states, but there are exceptions.
In HPO32, hydrogen has an oxidation number of +1, phosphorus has an oxidation number of +5, and oxygen has an oxidation number of -2.
