What is the oxidation number of Hg?
The oxidation number of mercury (Hg) can vary depending on the compound it is in. For example, in elemental form or in compounds where it is not bound to other elements, the oxidation number of Hg is 0. In compounds like HgCl2, where it is bonded to other atoms, its oxidation number is usually +2.
How can an elements Oxidation number be found?
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.
Where on the periodic table has a positive oxidation number?
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
How many oxidation numbers in each group?
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
Can nonmetals have positive and negative oxidation numbers?
Yes, nonmetals can have both positive and negative oxidation numbers depending on the specific compound they are a part of. For example, in compounds such as hydrogen peroxide (H2O2), oxygen can have an oxidation number of -1 whereas in compounds such as O2F2, oxygen can have a positive oxidation number.

How is burning wood an example of chemical change?
It is the oxidation of the elements of the chemicals that make up the wood - which are various organic compounds. These are released into the atmosphere as carbon dioxide, water vapour and oxides of other elements and compounds.

What does the common oxidation number mean?
The common oxidation number means any number that indicates the charge of atoms when an electron is either lost, gained, or shared in a chemical bond. It is known as the ion's number. Also, oxidation numbers in all atoms in a compound must add up to zero.
How is it possible for two different ionic compounds to contain. the same elements?
Because alkali metals, alkaline earth metals, and aluminum form ions with positive charges equal to the group number. Oxidation states are important. As an example, Iron can exist is a number of oxidation states. Oxygen prefers to be minus 2. However, just these two elements can produce FeO Fe2O3 Fe3O4 So 3 different (never mind 2!!) ionic compounds from the same elements
What colors are exhibited by chromium in its common oxidation states?
Chromium exhibits different colors in its common oxidation states. For example: Chromium(II) compounds are usually colorless. Chromium(III) compounds are typically green or violet. Chromium(VI) compounds are usually yellow or orange.
What trend do the oxidation numbers in group A follow?
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.
