Valence is how many bonds an atom can form. Oxidation number can be though of as being similar to the charge on an ion, and is based on the difference in electronegativity between bonded atoms. If something is bonded to a more electronegative element, its oxidation state is positive, and if it is with a less electronegative on the state is positive. In a neutral substance the sum of the oxidation states is always zero. Valence and oxidation states are related, though.
Example: In formaldehyde (CH2O) hydrogen has a valence of 1, oxygen a valence of 2, and carbon a valence of 4. Carbon is more electronegative than hydrogen, and less electronegative than oxygen. As a result, each hydrogen atom has an oxidation state of 1+ and the oxygen is in the 2- oxidation state. This puts carbon in an oxidation state of 0.

How many valence electrons is OF2?
Oxygen (O) has 6 valence electrons and fluorine (F) has 7 valence electrons. In OF2, there are a total of 18 valence electrons (6 from oxygen and 2 x 7 from fluorine).
What is argon valence number and electrons and oxidation number?
Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.
Is the oxidation number of an ion equal to the number of valence electrons the ion contains?
Yes, the oxidation number of an ion is equal to the number of valence electrons the ion contains. Valence electrons are the electrons in the outermost shell of an atom, and they are involved in forming chemical bonds, which also determines the oxidation state of an ion.
What is the relationship of valence electron and oxidation number?
The valence electrons of an atom determine its ability to form bonds and participate in chemical reactions. The oxidation number of an atom indicates the number of electrons it has gained, lost, or shared in a chemical compound. The valence electrons of an atom can help determine its oxidation number by considering how many electrons the atom needs to reach a stable configuration.
What is the difference between oxidation number and the number of valence electrons?
The oxidation number is the charge that an atom has when forming a compound, determined by the electron gain or loss. Valence electrons are the electrons in the outermost shell of an atom, which are involved in forming chemical bonds. While the oxidation number can vary based on the compound, the number of valence electrons remains constant for elements in the same group of the periodic table.

How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
Is the oxidation number of a compound equal to the number of valence electrons it has?
Not necessarily. The oxidation number of an atom is the charge it would have if all shared electrons were assigned to the more electronegative atom. The number of valence electrons an atom has helps determine its possible oxidation states, but it may not always correspond directly to the oxidation number in a compound.
What is an oxidation number and how is it related to Valence Electrons?
An oxidation number is a measure of the charge that an atom would have if the bonding were ionic. It indicates the number of electrons that an atom would gain or lose in a chemical reaction. Valence electrons are the outermost electrons in an atom’s electron cloud and play a key role in determining the oxidation number of an atom.
What is the number of valence electrons and oxidation number of strontium?
Strontium has 2 valence electrons because it is in Group 2 of the periodic table. The oxidation number of strontium is typically +2, as it tends to lose those 2 valence electrons to achieve a stable electronic configuration.
Is valence the same as oxidation number?
No, valence and oxidation number are not the same. Valence refers to the combining capacity of an atom based on its outer shell electrons, while oxidation number indicates the apparent charge of an atom in a compound or ion.
Why the oxidation number of sulphur is plus 6?
Sulphur has 6 valence electrons. So its maximum oxidation number is +6.
Aluminum is a metallic element with 3 valence electrons What is its oxidation number?
The oxidation number of aluminum is typically +3, as it tends to lose its 3 valence electrons to achieve a stable electron configuration.
