H = +1
s = +6
o = -2
Group 1 elements have an oxidation number of +1.
all the pure elements have zero oxidation state.....
Elements that have a single oxidation number include group 1 elements (e.g. sodium, potassium) which have an oxidation number of +1, and group 2 elements (e.g. magnesium, calcium) which have an oxidation number of +2.
all the pure elements have zero oxidation state.....
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
Elemental sulphur, like all other elements, has an oxidation number of zero(0). However, when combined with other elements into molecules, it displays different oxidation number.s H2S = -2 SO2 = +4 SO3 = +6 H2SO4 = + 6
+1 only for all elements (except for hydrogen) hydrogen can have +1 and -1 as their oxidation numbers.
To find the oxidation number for Zn in ZnSO4, you need to consider the oxidation numbers of the other elements. In ZnSO4, oxygen usually has an oxidation number of -2 and sulfur of +6. Since the compound is neutral, the sum of the oxidation numbers of all elements must equal zero. Hence, the oxidation number of Zn in ZnSO4 is +2.
The elements in column 13 of the periodic table (Group 13) typically have an oxidation number of +3 in their compounds. This includes elements such as boron, aluminum, gallium, indium, and thallium.
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.
-1.
Predominantly, the transition elements, but also hydrogen, nitrogen, and oxygen. Actually all elements that have reactions can have more than one oxidation number in the sense that their oxidation number is 0 when they are in pure form and usually is some other value when they are in compounds.
