The oxidation state of calcium is +2.
Calcium oxidation state is 2+.
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
The oxidation number of Calcium (Ca) is +2
the oxidation number is 0
The element oxidation state is a chemical property: it is zero for all elements.
0, 1 and 2 oxidation states
The oxidation state of an element is determined by the number of electrons the element needs to lose or gain to have a full valence electron shell.
Oxidation state of any element in its elemental state is 0
Mercury's most common oxidation state is +2
The highest oxidation state for an element is +7, but this is not unique to any one element: All of the halogen elements except fluorine have oxyacids with this oxidation state.
all the pure elements have zero oxidation state.....
The oxidation state of any lone element is zero.
if you mean iodine in its elemental state, the the oxidation state is zero, as for any element in its elemental state, the oxidation state is always zero
