2 oxidation state
The highest oxidation state ever achieved by an element is +8. This oxidation state can be found in 3 elements: Osmium, Ruthenium and Xenon.The synthetic element Hassium is also expected to have this oxidation state.
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The oxidation state of calcium is +2.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
Some examples of elements that commonly form cations with positive oxidation states include alkali metals such as sodium (Na+) and potassium (K+), alkaline earth metals such as magnesium (Mg2+) and calcium (Ca2+), and transition metals like iron (Fe3+) and copper (Cu+).
O = -2 oxidation state H = +1 oxidation state
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
S = +4 oxidation state O = -2 oxidation state
Platinum is connected to two anionic Chloride ligands and two neutral Ammine ligands Platinum = +2 oxidation state Chlorine = -1 oxidation state Nitrogen = -3 oxidation state Hydrogen = +1 oxidation state
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
This oxidation state is 1.
