Bromine has an oxidation number of negative one, except when with oxygen or flourine.
The oxidation number of carbon in CBr4 is +4 because bromine is more electronegative than carbon and is assigned an oxidation number of -1 each. Since there are four bromine atoms in CBr4, the total oxidation number of bromine is -4. The sum of the oxidation numbers in a compound must equal zero, so the carbon must have an oxidation number of +4 to balance the negative oxidation numbers from the bromine atoms.
In CH2Br2, carbon has an oxidation number of -2 because hydrogen has an oxidation number of +1 and bromine has an oxidation number of -1. The sum of the oxidation numbers in a neutral compound is zero.
Actually there are a few KBrO3 or NaBrO3 etc - in the bromate ion, bromine is in oxidation state +7
The oxidation number of bromine in bromine trifluoride is +3. This is because each fluorine atom has an oxidation number of -1, and since there are three fluorine atoms in bromine trifluoride, the overall charge must balance out to zero.
The oxidation number of bromine in HOBr is +1. This is because the oxidation number of oxygen is typically -2 and the overall compound is neutral, so the oxidation number of hydrogen is +1. This leaves bromine with an oxidation number of +1 to balance the compound.
The oxidation number of carbon in CBr4 is +4 because bromine is more electronegative than carbon and is assigned an oxidation number of -1 each. Since there are four bromine atoms in CBr4, the total oxidation number of bromine is -4. The sum of the oxidation numbers in a compound must equal zero, so the carbon must have an oxidation number of +4 to balance the negative oxidation numbers from the bromine atoms.
In CH2Br2, carbon has an oxidation number of -2 because hydrogen has an oxidation number of +1 and bromine has an oxidation number of -1. The sum of the oxidation numbers in a neutral compound is zero.
Bromine oxidation causes ozone depletion. Bromine utilizes the oxygen from ozone to deplete it.
Actually there are a few KBrO3 or NaBrO3 etc - in the bromate ion, bromine is in oxidation state +7
The oxidation number of bromine in bromine trifluoride is +3. This is because each fluorine atom has an oxidation number of -1, and since there are three fluorine atoms in bromine trifluoride, the overall charge must balance out to zero.
The oxidation number of bromine in HOBr is +1. This is because the oxidation number of oxygen is typically -2 and the overall compound is neutral, so the oxidation number of hydrogen is +1. This leaves bromine with an oxidation number of +1 to balance the compound.
The oxidation number of Al in Al2Br6 is +3. Each bromine atom has an oxidation number of -1, and since the compound is neutral, the sum of the oxidation numbers must equal zero. Hence, each Al atom must have an oxidation number of +3 to balance the -6 from the bromine atoms.
The oxidation number of bromine in KBr is -1. In ionic compounds, the oxidation number of the cation (K+) is always equal to its charge, which is +1. Therefore, the oxidation number of bromine must be -1 to balance the overall charge of the compound.
Each Br atom has an oxidation number of zero.
In AlBr3, aluminum (Al) has an oxidation number of +3, while each bromine (Br) atom has an oxidation number of -1. This is because aluminum typically forms 3+ cations, while bromine typically forms 1- anions.
Bromine typically exists in the -1 oxidation state in ionic compounds. In elemental form or as part of a molecule, bromine can have various oxidation states ranging from -1 to +7.
The oxidation number of Br- is -1. Bromine typically has an oxidation state of -1 when it forms an ion by gaining one electron.
