An element that may have an oxidation number of 4 or 4?
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
What is the oxidation number of oxygen?
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
What are the 10 rules in assigning oxidation numbers?
The oxidation number of an uncombined element is zero. The sum of oxidation numbers in a neutral compound is zero. Group 1 metals have an oxidation number of +1, and Group 2 metals have an oxidation number of +2. Oxygen usually has an oxidation number of -2. Hydrogen usually has an oxidation number of +1. Fluorine always has an oxidation number of -1. The more electronegative element in a binary compound is assigned its typical oxidation number. Within a polyatomic ion, the sum of oxidation numbers equals the charge of the ion. In a coordination complex, the oxidation number of the metal ion is equal to the overall charge of the complex. Remember that these rules are guidelines and may vary based on the specific compound or situation.
Oxidation number Cl?
Elemental Cl has zero O.number . In compounds it depend upon charge of ionAtomic chlorine has 0 as oxidation number. The oxidation state of chlorine ion, which is made with metals is -1. When forming oxychloride anions, the oxidation state of chlorine may change from 0 to +7.
Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
What element have oxidation numbers plus 1 and -1?
Cl,Br and Iodine may have oxidation no +1 and -1

What causes oxidation numbers?
Oxidation is a process of loss of electron(s) from an element or ion. After the lose of electron, the element becomes positively charged or if an undergoes oxidation then its positive charge is increased. For instance Sodium metal has 11 electrons and it can easily lose one electron (removing another electron is so difficult and it needs high energy) and becomes Na(+) ion. So its oxidation number is one.Hence, oxidation number refers number of electrons lost by an ion or element.Reverse of oxidation is called reduction or gain of electrons by an element or ion, in which the oxidation number is decreased. So in reduction process oxidation number is decreased.Oxidation number may be positive or negative for ions and it must be zero for an element. If it is positive then the ion is called cation and if negative then the ion is known as anion. It entirely depends on the property of losing or gaining of electrons by an element or ion.By,Dr M Kanagasabapathy Ph D,Asst.

What number identify an element?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
Is an oxyanion named based on the amount of a metal in the ion?
No, the name of an oxyanion is not based on the amount of a metal in the ion. The name of an oxyanion is determined by the oxidation state of the element and the number of oxygen atoms in the ion. The metal in the ion may play a role in determining the charge or oxidation state of the element, but it does not directly determine the name of the oxyanion.
What's the difference between oxidation state and oxidation number?
oxidation is the process that occurs when a substance combines with oxygen, or any chemical process where there is a loss of electrons charge is also known as the oxidation number (oxidation state). which is a number assigned to an element, to represent how many electrons it has. for example hydrogen has a charge of +1 oxygen has a charge of -2
It may be possible that oxidation number of oxygen in ko3 is13?
The oxidation number of oxygen in compounds is typically -2, unless it's a peroxide where it is -1. In KO3, the oxidation number of potassium is +1, so for the compound to be neutral, the oxidation number of oxygen would have to be -2.
Metals may naturally oxidize and virtually always?
Metals may naturally oxidize and virtually always have the same oxidation number. An oxidation number is assigned to an element in chemical combination that represents the number of electrons lost or gained.
