An element that can have multiple oxidation states typically has a partially filled d or f subshell, allowing it to lose varying numbers of electrons. Transition metals are common examples, as they can exhibit different oxidation states due to the involvement of both their outermost s and inner d electrons in bonding. Additionally, elements with variable valence can form different compounds and exhibit diverse chemical behaviors depending on their oxidation state.

How can an element have fractional valencies or two integral valence states at a time?
An element can have fractional valencies when it forms complex ions or compounds with multiple oxidation states. This occurs when the element shares electrons unevenly or when it exhibits variable oxidation states. For an element to have two integral valence states at the same time, it would need to exist in different chemical environments simultaneously, often in the form of different compounds or complexes exhibiting different oxidation states.
How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
How is the unknown oxidation state of an element within a compound determined?
The unknown oxidation state of an element in a compound can be determined by using a set of rules based on the known oxidation states of other elements in the compound. First, assign oxidation states to all known elements according to standard rules, such as those for group elements and common ions. Then, apply the principle that the sum of oxidation states in a neutral compound must equal zero or match the charge of a polyatomic ion. By solving the resulting equation, the unknown oxidation state can be deduced.
Why oxidation state of carbon is zero in C6H12O6?
The sum of oxidation states in a neutral compound is zero. In glucose (C6H12O6), carbon is the most electronegative element and has an oxidation state of -4 (H=+1, O=-2). With six carbon atoms, each with an oxidation state of -4, the total oxidation state for carbon is zero.
How can an element have fractional valencies or two integral valence states at a time?
An element can have fractional valencies when it forms complex ions or compounds with multiple oxidation states. This occurs when the element shares electrons unevenly or when it exhibits variable oxidation states. For an element to have two integral valence states at the same time, it would need to exist in different chemical environments simultaneously, often in the form of different compounds or complexes exhibiting different oxidation states.
What is the oxidation nu?
Oxidation number is oxidation states of an element. It can be positive or negative.
What are the different oxidation states of a metal that exhibits multiple oxidation states?
Metals that exhibit multiple oxidation states can have different levels of positive charge, known as oxidation states. These can vary depending on the compound the metal is in. For example, iron can have oxidation states of 2 and 3.
What element has oxidation states of 2 and 3 only?
The element with oxidation states of +2 and +3 only is chromium (Cr).
How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
What is disproportionality?
In these reaction, an element simultaneously undergoes oxidation as well as reduction. This is possible only when the element exhibits minimum three different oxidation states and on the reactant side, it is present in an intermediate oxidation state while higher and lower oxidation states are exhibited by it in the form of products.
How can one determine the oxidation number of an element in a chemical compound?
To determine the oxidation number of an element in a chemical compound, you need to follow these steps: Identify the element in the compound. Determine the common oxidation states for that element. Assign the oxidation number based on the compound's overall charge and known rules for assigning oxidation numbers. By following these steps, you can accurately determine the oxidation number of an element in a chemical compound.
Where is the oxidation number in the periodic table?
The oxidation number is not specifically listed on the periodic table. Oxidation numbers are assigned based on rules and guidelines that depend on the chemical properties and bonding of each element. Different elements can have multiple oxidation states, which can vary depending on the compound or molecule in which they are found.
What is the oxidation state of an element?
In chemistry, the oxidation state is a number assigned to an element as an indicator of the degree of oxidation of an atom in a chemical compound."The charge an element would have if it were an ion "Oxidation state is the same as the oxidation number. It is an indicator of the degree of oxidation of an atom in a chemical compound.
How do you get the oxidation number of an element?
To determine the oxidation number of an element, consider its usual oxidation state based on its position in the periodic table and the known oxidation states of other elements in the compound. In a neutral compound, the sum of the oxidation numbers must equal zero, and in an ion, the sum must equal the charge of the ion. Use these rules to assign the oxidation number of the element.
Which element shows plus 3 and plus 4 oxidation states?
cerium
