The highest known oxidation state is +8 in the tetroxides of ruthenium, xenon, osmium, iridium, hassium, and some complexes involving plutonium; the lowest known oxidation state is −4 for some elements in the carbon group.
Carbon dioxide, in which all four bonds on the carbon are to oxygen, is in the highest oxidation state. The alkane oxidation state is the most reduced.Sep 12, 2021
ManganeseManganese shows the highest oxidation state +7.
So, oxidation state of Mn iss highest in KMnO4.
The highest oxidation state of an element is determined using the periodic table by the group in which it is located. Metals in all compounds have a positive oxidation state. In compounds with non-metals, hydrogen has an oxidation state of +1, and an oxidation state of -1 with metals.
–4The oxidation number of carbon in methane (CH4) is –4, while its oxidation number in carbon dioxide is +4. The oxidation number of hydrogen in all compounds is +1. The oxidation number of oxygen in its elemental form is 0, while its value in carbon dioxide and water is –2.
Answer: Both fluorine and oxygen have small size, high electronegativity and also high negative electron gain enthalpy. They can oxidise a metal to the highest oxidation state. Thus, the highest oxidation states are shown in the oxides and fluorides of transition metals.
A few of the chemical trends to be found in the first transition series may be capsulized. 1. From titanium to manganese the highest oxidation state exhibited, which usually is found only in oxo compounds, fluorides, or chlorides, corresponds to the total number of 3d and 4s electrons in the atom.
+8The highest oxidation state of a metal is exhibited in its oxide or fluoride only. This is because fluorine (F) and oxygen (O)are the most electronegative elements and the highest oxidation state shown by any transition element is +8. Explore more such questions and answers at BYJU'S.
