Oxidation state of any element in its elemental state is 0
The oxidation state of calcium is +2.
The element with the lowest oxidation state on the periodic table is Francium.
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
the oxidation number is 0
Vanadium is an element that commonly exhibits an oxidation state of +5.
In amalgams, the oxidation number of mercury is typically 0 because it is in its elemental form. Amalgams are alloys of mercury with other metals, where the mercury atoms do not change their oxidation state.
Hydrogen is an element that can have an oxidation state of -1 when it is part of a hydride ion, such as in lithium hydride (LiH).
