oxidation number of Iodine in IF4
F is -ve and I is +ve
therefore,
x-4=+1
x=5
manganese is a 3d element. +2 is the oxidation number in this ion.
Think about it, the overall charge of CaH2 is neutral (meaning a charge of 0). One of the oxidation rules states that H has a charge of -1 if it is apart of a hydride (Ex LiH, CaH2 is also a hydride). Because there are 2 Hs, it's charge would be -2. If you add the charge of calcium which is 2 with the hydrogens charge -2 you would get 0, which is right because the molecule is neutral. 1- Apex
The Oxidation number is an apparent charge on a single atom in an ion or molecule in Nitrate the Oxidation number of Nitrogen is +5 and -6 for three oxygen atoms (-2 each) so net charge on Nitrate ion is -1.
An oxidation number of 3 means that the element has a charge within the compound of +3. For example: AlCl3 (Aluminum chloride). Cl has a charge of -1 because it gains 1 electron during bonding to become stable so Al has to have a charge of +3 to balance the overall charge of the compound to zero.
Nitrogens oxidation number is plus five. Oxygen's number is minus two.
SO2 is neutral. Please refer to the oxidation states. Since all oxidation numbers added together in a compound must equal zero. Which means that : S+(-2*2)=0, so S has an oxidation number as +4, in which O2 has an oxidation number of -2*2 = -4. Just find out the oxidation number of the compounds each time through equation and you'll know the charge. Easy.
