What is the oxidation number of hydrogen?
+1
Hydrogen has an oxidation number of +1 in most compounds. The major exception is when hydrogen is combined with metals, as in N a H \ce{NaH} NaH or L i A l H X 4 \ce{LiAlH4} LiAlHX4. In these cases, the oxidation number of hydrogen is −1 .
What is the oxidation number for HBR?
Since H is in column 1 of the periodic table, it will share 1 electrons and use an oxidation state of 1 . Since Br is in column 7 of the periodic table, it will share 7 electrons and use an oxidation state of 7 .
What is the oxidation for Br?
−1
The most stable oxidation state of the element is −1, in which bromine occurs naturally. But oxidation states of 0 (elemental bromine, Br2), +1 (hypobromite, BrO−), +3 (bromite, BrO−2), +5 (bromate, BrO−3), and +7 (perbromate, BrO−4) are also known.
What is the oxidation number of H and Cl in HCL?
-1
The oxidation number of hydrogen is +1 and the oxidation number of chlorine is -1 .
What is the oxidation number of hydrogen in H2?
0
The oxidation number for elemental hydrogen, H2, is 0.
What is the oxidation number of Br in HOBr?
Hypobromous acid is a weak, unstable acid with the chemical formula HBrO, where the bromine atom is in the +1 oxidation state.
What is the oxidation of Cl in HCl?
So, finding the oxidation number of chlorine in: -HCl, this molecule has ${{H}^{+}}$ and $C{{l}^{-}}$, as hydrogen has a +1, then chlorine will have, +1 + Cl = 0, so Cl = -1. So, chlorine has -1 in HCl.
What is the oxidation number of Cl in ClO?

What is the oxidation number of H2 in this reaction?
This is an electrically neutral compound, so the sum of the oxidation states of the hydrogen and oxygen must be zero….
| Element | Usual oxidation state | Exceptions |
|---|---|---|
| Oxygen | Usually -2 | Peroxides and F2O (see below) |
| Hydrogen | Usually +1 | Metal hydrides (-1) (see below) |
| Fluorine | Always -1 |
What is the oxidation number of chlorine gas?
Oxidation number means that the number of electrons either lost or gained by an atom of an element during compound formation. The oxidation number of chlorine are +1,+3,+5,+7 and -1. However for Chlorine gas, the oxidation number (Cl2) is zero.
What are the rules for the oxidation number?
