Oxidation number of a free element is 0. Ex: Ag 2= 0
For Mg the oxidation no is +2 while it is -2 for oxygen.
Zn is a d block element. Oxidation number of it is +2.
Iron
0- any element by itself has an oxidation number of 0.
The oxidation state of calcium is +2.
Oxidation number of a free element is 0. Ex: Ag 2= 0
For Mg the oxidation no is +2 while it is -2 for oxygen.
Zn is a d block element. Oxidation number of it is +2.
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.
Mercury's most common oxidation state is +2
Zn is a d block element. Oxidation number of it is +2.
+4
Iron
+2 implies that 2 electrons are lost by the element. -2 implies that 2 electrons are gained by the element
+2 implies that 2 electrons are lost by the element. -2 implies that 2 electrons are gained by the element
0- any element by itself has an oxidation number of 0.
