oxygen
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).
Mercury's most common oxidation state is +2
Oxygen (in Oxide ions)
An oxidation state is a number that is assigned to an element in a chemical combination.
The oxidation state of calcium is +2.
The element with the lowest oxidation state on the periodic table is Francium.
It is the square root of a piece of cheese after I bit it off and eaten a cracker.
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
The most common oxidation state of -2 would be Oxygen.
the oxidation number is 0
In chemistry, for an element to be reduced means that it gains electrons during a chemical reaction. This process decreases the oxidation state of the element, making it more negative. Reduction often occurs simultaneously with oxidation, where another element loses electrons; together, these processes are part of redox (reduction-oxidation) reactions.
Vanadium is an element that commonly exhibits an oxidation state of +5.
