Group 16 on the Periodic Table has elements that form a -2 charge when they bond ionically with metals. This group contains the very common elements oxygen and sulfur. They are usually referred to simply as group 16, group 6A, the "oxygen group," or by their old-fashioned name, the chalcogens.
The highest oxidation state of a transition metal is typically found in group 7b (Mn, Tc, Re) elements, reaching up to +7 oxidation state.
+2
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
The most common oxidation state of -2 would be Oxygen.
the answer is..... well figure it out yourself you dumb as*
The most common negative oxidation state in Group 13 elements is -3. This is particularly seen in compounds where these elements form three bonds with more electronegative species.
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 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 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.
1+ (it is in group 1)
In KNO3, the nitrogen atom has an oxidation state of +5. This is because potassium (K) is in Group 1 and has an oxidation state of +1, and oxygen (O) is in Group 6 and has an oxidation state of -2. To balance the charges, nitrogen must have an oxidation state of +5.
The oxidation numbers in group A elements typically increase by one as you move from left to right across the periodic table. For example, group 1 elements usually have an oxidation state of +1, while group 7 elements typically have an oxidation state of -1.
Becase group one only needs one valence electron to reach a stable oxidation state.
Boron (B, atom number 5, the 1ST member of group 13) has an oxidation state of +3, it is rather a metaloid, even more than Al (2nd member), so it forms an acidic oxide B2O3.
The oxidation state of NO is +1. This is because nitrogen is in Group 15 of the periodic table and typically has an oxidation state of -3. In NO, oxygen is more electronegative than nitrogen, causing nitrogen to have a formal oxidation state of +1 to balance the charge.
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
