Group 3 elements have an oxidation number of +3. This is because they have three valence electrons that are typically lost in chemical reactions, resulting in a +3 oxidation state.
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.
To determine an element's oxidation number on the periodic table, consider its group number (vertical column). Elements in Group 1 typically have an oxidation number of +1, Group 2 is +2, Group 7 (halogens) is typically -1, and Group 6 is often -2. Transition metals have variable oxidation states based on the compound. Remember that the oxidation number is the charge an atom would have if electrons were transferred completely.
An element's oxidation number is related to the group on the periodic table because elements in the same group have similar chemical properties due to their similar electron configurations. The number of valence electrons an element has, which is determined by its group number, impacts its ability to gain or lose electrons and thus determines its common oxidation states.
It can be a any group. Generally they shows +2 in group 2.
The oxidation number of gallium is typically +3. This is because gallium belongs to Group 13 of the periodic table, and elements in this group typically exhibit an oxidation state of +3 in their compounds.

The vertical columns of the periodic table are called groups. The horizontal rows of the periodic table are called periods. The number of electron shells an atom has corresponds to the number period of the periodic table it is located in. The oxidation number or number of valence electrons an atom is depicted by the group it is in. For example: Calcium (Ca) has an oxidation number of +2 and has 2 valence electrons( outermost electrons) which means it belongs to group 2 of the periodic table called the "alkali earth metals".
the oxidation number, determined by its group on the periodic table.
The oxidation number of gallium is typically +3. This is because gallium belongs to Group 13 of the periodic table, and elements in this group typically exhibit an oxidation state of +3 in their compounds.
The oxidation number of iodide is -1. Iodine is in Group 17 of the periodic table, commonly known as the halogens, which typically have an oxidation number of -1 when in ionic compounds.
In NaBr, sodium (Na) has an oxidation number of +1 since it belongs to group 1 of the periodic table. Bromine (Br) has an oxidation number of -1 since it is a halogen.
An element with an oxidation number of +1 is typically found in group 1 of the periodic table, such as sodium (Na) or potassium (K). An element with an oxidation number of -1 is typically found in group 17 of the periodic table, such as chlorine (Cl) or fluorine (F).
