If element X forms the oxides XO and X2O3 the oxidation numbers of element X are what?
Oxygen forms a -2 ion.
x0 - x= +2.
The compound overall needs to be neutral, so you add up all the charges from the oxygen and add whatever you need to make it neutral.
eg:
FeO - oxidation state of iron = +2, since oxygen forms -2 and compound is overall neutral.
Fe2O3 - -6 from the oxygen. So you need to add +3, and there are two Fe's so you divide it by two - therefore iron is +3.
Hope that helps.

What charge is the oxidation number of an element?
The charge of an element is based on its oxidation number, which is the number of electrons that an atom loses, gains, or shares when it forms a chemical bond. Oxidation numbers can be positive, negative, or zero, depending on the element and the chemical compound it is part of.
What element has -1 as an oxidation number?
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
What is the oxidation number of the first twenty elements?
The oxidation number of an element is the charge that atom has when it forms ions. The oxidation number varies depending on the compound the element is in. There isn't a strict rule for the oxidation numbers of the first twenty elements as they can exhibit various oxidation states depending on the specific compound they are present in.

What is oxide atomic number?
The atomic number of oxide depends on the specific element it is composed of. For example, the atomic number of oxygen, which commonly forms oxides, is 8. Other elements forming oxides will have their own unique atomic numbers.
What is formed when an element is burned in air or oxygen?
When an element is burned in air or oxygen, it forms oxides. The type of oxide formed depends on the reactivity of the element with oxygen. For example, carbon forms carbon dioxide while magnesium forms magnesium oxide.
What element has an Oxidation number of plus 1 and - 1?
Hydrogen it depends on the other element if it is part of a compound
Oxidation number of an uncombined element?
The oxidation number of an uncombined element is zero. Uncombined elements, also known as elemental forms, have no charge and are considered to have an oxidation number of zero in their pure state.
When metals react with the oxygen in air what it is called?
When metals react with the oxygen in the air, it is called oxidation. This process forms metal oxides on the surface of the metal, which can lead to rusting or tarnishing.
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 is the oxidation number of P?
Phosphorous, or P, has a zero oxidation number in the element. Common oxidation numbers are:- It has a -3 in phosphides, where it forms the P3- ion It has a +3 in oxidation number in for example P4O6, and PCl3 It has a +5 oxidation number in for example P4O10 and PCl5
Which element is a solid and forms rust when reacted with air?
The element is iron.Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture.
