Positive oxidation numbers are most common with the metals - groups 1 to 13. However there are many well known compounds where non-metals have positive oxidation numbers- for example NaClO4 where Cl has an oxidation number of +7
Every element on the Periodic Table has an OXIDATION NUMBER of zero, including Lithium.
The element with the lowest oxidation state on the periodic table is Francium.
Oxidation numbers generally become more positive from left to right across a period and more negative down a group on the periodic table. This trend is due to changes in the number of valence electrons as you move across and down the table, impacting how likely an atom is to gain or lose electrons.
The oxidation number for Li, or Lithium, is Li+1. Lithium is in the first family on the Periodic Table. Since the element wants to become stable, and it only it needs 8 valence electrons. So therefore, it has to lose an electron. Losing an electron will make it a positive oxidation number.
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.

The most common oxidation states in the periodic table are +1, +2, +3, -1, -2, -3. These oxidation states are frequently observed in elements based on their position in the periodic table and their electron configuration.
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".
In English please ?I
-1.
The oxidation number of a chemical tells how many electrons it will gain or lose in a reaction. A positive oxidation number means that it will lose electrons, and a negative means it will gain them. A chemical with an oxidation number of 2+ would usually lose 2 electrons in a reaction.All of the Alkali earth metals (second column of the periodic table) have an oxidation number of 2+.
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.
The oxidation number for Li, or Lithium, is Li+1. Lithium is in the first family on the Periodic Table. Since the element wants to become stable, and it only it needs 8 valence electrons. So therefore, it has to lose an electron. Losing an electron will make it a positive oxidation number.
The oxidation number of an element is typically determined based on its position on the periodic table and known oxidation rules. For example, in compounds, the sum of oxidation numbers must equal the overall charge. For atoms in their elemental form (such as O2 or Na), the oxidation number is zero.
