-2 for each O, +7 for Mn
In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
In LiH, the oxidation number of Li is +1 and the oxidation number of H is -1. This is because lithium typically has a +1 oxidation state and hydrogen typically has a -1 oxidation state in ionic compounds.
The oxidation number of the ion F1- is -1.

For HClO oxidation No. is '0' . It is a neutrally charged molecule. However, The chlorine atom is in oxidation state (+1). How so???? you may ask . Using oxygen as that standard at '-2' , and hydrogen at '+1' We create a little sum +1 + Cl -2 = 0 ( overall charge on the molecule). Collecting terms Cl - 1 = 0 Cl = + 1 as required. NB When dissolved in water chlorine disproportionates. That is it simultaneously oxidises and reduces., Cl2(aq) = Cl^(+)(aq) + Cl^(-)(aq) It reacts with water molecules to form ;- Cl2 + H2O = HClO + HCl The supply of drinking water from public sources has chlorine bubbled through to act as a bacteriocide (kill the bugs). So tap/faucet water is a very weak solution of hydrochloric acid(HCl) and Hydrogen chlorate(bleach)(HClO). It won't harm you, because the solution is so weak, but just enough to kill the bugs.

The oxidation number of the ion F1- is -1.
The oxidation number for iodine in IF is -1. Fluorine always has an oxidation number of -1 in compounds.
Pottasium has +1 oxidation number.Iodine has -1 oxidation number.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
In AlOH^1-, oxygen typically has an oxidation number of -2. Since the overall charge of AlOH^1- is -1, the oxidation number of Al can be calculated as follows: (oxidation number of Al) + (oxidation number of O) + (oxidation number of H) = -1. Solving for Al gives an oxidation number of +3.
The oxidation number of Li in LiBr is +1, and the oxidation number of Br is -1.
The oxidation number of hydroxide (OH-) is -1. This is because oxygen typically has an oxidation number of -2, and hydrogen has an oxidation number of +1. In this case, there is one oxygen atom and one hydrogen atom, resulting in an overall oxidation number of -1.
