Enter just an element symbol to show the common and uncommon oxidation states of the element. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 你可以用小括号()或括号[ ]。 What is an oxidation state?
Oxidation state of an atom is the signed number of lack or access electrons compared to its neutral state. Historically it referred to the number of removed electrons (hence the name), but in modern chemistry both types of ions (lost or gained electrons) are included....

Cr2O3, and Cr-containing alloys using density functional theory20,21,22,23. While each of these approaches provides its own insights on the nature of point defects’ charge state, mobility, and formation energies, there have been no efforts to unite the results and insights of a variety of...
As it is known, in compounds, oxidation state of oxygen is −2 and hydrogen is +1. In simple carbon compounds, oxidation state of C can be calculated by equalizing the sum of all C, H, and O atoms' oxidation state to zero, unless the compound has a charge. Accordingly, the ...
Key principles of alloy oxidation are discussed, with emphasis on Cr2O3 and Al2O3 formation on nickel-, cobalt, and iron-base alloys. The various special cases of alloy oxidation, which are quantifiable to varying degrees, are presented schematically. The important competition between surface ...

The oxidation state of mercury ions can be expressed by either a Roman numeral or a special name. The mercurous ion, or mercury (I) ion, has a +1 oxidation state, while the mercuric ion, or mercury (II) ion, has a +2 oxidation state....
2 with uranium antimonide following the published strategy [6, 26, 27] of R.K. Grasselli. Two structural variants USbO5 and USb3O10 exist that can interconvert. Good arguments exist for the formal identical oxidation state of +5 for both cationic species rendering strong covalency in their ...
