Oxidation Numbers

The oxidation number for each sulfur atom in peroxodisulfate ion (S2O8 2-) is +6 because oxygen has an oxidation number of -2, and the overall charge of the ion is 2-.

Zinc's electron configuration is [Ar] 3d10 4s2. It readily loses both its 4s electrons to achieve a full d shell, resulting in an oxidation state of +2 in most of its compounds. The stable 3d10 configuration following the loss of electrons contributes to zinc's preference for the +2 oxidation state.

In magnesium bromide (MgBr2), magnesium has an oxidation number of +2 and each bromine atom has an oxidation number of -1. This is because magnesium typically forms 2+ cations, while bromine forms 1- anions.

The oxidation number for an atom is determined by the number of electrons it gains or loses to achieve a stable electron configuration. For the configuration 1s22s22p63s22p5, sulfur (S) has an oxidation number of -2, as it has gained two electrons to achieve a full valence shell of 8 electrons.

C=4

n= -3

oxygen is -2

OCN has net charge of -1 so here is my expalnation

we will take C as unknown

-2+x-3=-1

x=4

now N is the unknown :

-2+4+x=-1

x=-3

and Oxygen is always -2 except peroxides and others cases...

hope i helped !

The oxidation number of carbon in CH3OH is -2. This is because hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2. By assigning these values to the other atoms in the molecule, we can determine that carbon must have an oxidation number of -2 to balance the overall charge of the molecule.

In Ag NO3 the oxidation number of Ag (Silver) is 1+, the oxidation number of N (Nitrogen) is 5+, and the oxidation number of O (Oxygen) is 2-.

Oxidation numbers help determine the amount of electrons an atom has gained, lost, or shared in a compound. They are useful for balancing chemical equations, predicting the reactivity of elements, and identifying the type of chemical bond present (ionic or covalent). Additionally, oxidation numbers play a crucial role in understanding redox reactions and determining the oxidation state of elements in compounds.

It is the square root of a piece of cheese after I bit it off and eaten a cracker.

The oxidation number of bipyridine is 0 because each nitrogen atom has an oxidation number of -3 in this aromatic compound, and each carbon atom has an oxidation number of -2. The sum of the oxidation numbers in bipyridine adds up to 0.

those elements which can donate two electrons will possess plus two oxidation state like calcium , magnesium ,etc...

No, covalent molecules do not have oxidation numbers. Oxidation numbers are assigned to individual atoms in ionic compounds based on their electronegativity and sharing of electrons. In covalent molecules, electrons are shared between atoms, making it difficult to assign oxidation numbers.

The oxidation number of carbon in formaldehyde (HCHO) is +2. In this molecule, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. By applying the rules for assigning oxidation numbers in a compound, we can determine that carbon has an oxidation number of +2.

Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1.

But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds

Yes, metals can have positive oxidation numbers when they lose electrons to form cations. However, metals typically do not have negative oxidation numbers since they usually do not gain electrons to form anions.

+1 is the oxidation state of Hg in Hg2CI2.

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.

The oxidation number of copper (II) is +2. This means that copper has lost two electrons in a chemical reaction and has a charge of +2.

The oxidation number of hydrogen is +1 and the oxidation number of oxygen is -2. Since the compound is neutral, the oxidation number of silicon in H4SiO4 is +4.

The oxidation number of Fe in Fe2 is +2. Iron typically forms ions with a +2 oxidation state.

The common oxidation number for halogens is -1. This is because halogens have 7 electrons in their outer shell and tend to gain 1 electron to achieve a full valence shell, resulting in an oxidation number of -1.

An element's oxidation number is determined based on its electron configuration and the number of electrons it gains or loses when forming chemical bonds. The rules for assigning oxidation numbers depend on the type of element and the chemical compound in which it appears. Oxidation numbers help to track the flow of electrons in chemical reactions.

The oxidation number of bismuth in Bi2O3 is +3. In the compound Bi2O3, oxygen has an oxidation number of -2 (since it is in its standard state), so the oxidation number of bismuth must be +3 to balance the charge.

In N2H4, the oxidation number of nitrogen (N) is -2. Each hydrogen (H) has an oxidation number of +1.
