What does it mean to say an element has an oxidation number of 2?
An oxidation number of 2 means the element has lost or gained 2 electrons in a chemical compound. The oxidation number is a measure of the element's ability to combine with other elements.
What do the oxidation number of plus 2 and -2 imply?
The oxidation number illustrates the number of electrons that a particular atom has partially/completely donated/accepted. +2 stands for donation of two electrons such as magnesium in magnesium salts. The oxidation number of -2 stands for obtaining two electrons such as an oxygen atom in an oxide.
What are the oxidation numbers of kmno4 plus kno2 plus h2so4 equals mnso4 plus H2O plus kno3 plus k2so4 oxidation numbers?
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
What is the oxidation number mn2?
manganese is a 3d element. +2 is the oxidation number in this ion.
What does it mean if a chemicals oxidation number is plus 2?
It can mean that the element has lost 2 electrons to form a pos. 2 ion. Or it can mean that in a particular compound (or polyatomic ion) that atom is combined with more electronegative elements in a particular combination that the rules used to assign oxidation numbers gives this atom a +2 oxidation number.
What is the oxidation number for each element in Mg plus O?
The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.

In the following compound al2o3 aluminums oxidation number is plus 3 and oxygen's oxidation number is?
-2
In the compound H2 S hydrogen has an oxidation number of 1 plus and sulfur has an oxidation number of?
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
What does the oxidation number of an element tell you?
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
What is the oxidation number for calcium and nitrate?
Calcium is a element. Nitrate is a ion. Calcium shows +2.
What is the oxidation number of a free element?
Oxidation number of a free element is 0. Ex: Ag 2= 0
