To predict an element's oxidation number, you can use the rules based on the Periodic Table and chemical bonding principles. For example, in many cases, elements prefer to have a full valence shell, so they will gain or lose electrons to achieve that stable electron configuration. Additionally, the group number of an element can provide a general idea of its typical oxidation number.
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.
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.
The group number of an element often corresponds to the typical oxidation state it will exhibit. For main group elements (groups 1, 2, 13-18), the oxidation state is typically equal to the group number. However, transition metals (groups 3-12) can exhibit multiple oxidation states due to their partially filled d orbitals.
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 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.
Knowing lithium's oxidation number allows us to predict how many electrons it will lose or gain when forming compounds. Lithium typically has an oxidation number of +1, so it tends to lose one electron to achieve a stable electron configuration. This helps determine the types of compounds it will form, such as lithium oxide (Li2O) or lithium carbonate (Li2CO3).

Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Elements in group 2 mostly takes the oxidation number +II.
