The oxidation number of the ion F1- is -1.
In K2MnF6, +1 for K, +4 for Mn and -1 for F In SbF5, +5 for Sb and -1 for F In KSbF6, +1 for K, +5 for Sb and -1 for F In MnF3, +3 for Mn and -1 for F In F2, 0 for F
The oxidation number of copper (Cu) in CuF2 is +2. The oxidation number of fluorine (F) in compounds is almost always -1, and since there are two fluorine atoms in CuF2, the total negative charge is -2, which balances with the +2 oxidation state of copper.
+1 for hydrogen -1 for fluorine
O.S of K = +1 O.S. of Ta = +5 O.S. of F = -1
O.S. of N = +1 O.S. of F = -1 O.N. of cpd = 0

The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. 'H' always has an oxidation number of +1. There are three of these atoms in the compound giving +3. To cancel out this positive number, the 'B' must equal -3.
The oxidation number of Cl in ClF3 is +3. This is because fluorine (F) is more electronegative than chlorine (Cl) and will take on an oxidation number of -1, leaving chlorine with an oxidation number of +3 to balance the overall charge of the compound.
The oxidation number of F, or Fluorine, is F-1. Since it is in the seventh group on the periodic table, it has seven valence electrons. It needs to get eight valence electrons to be stable, so it will gain one electron.
The oxidation number of iodine in IF is +1 because fluorine is more electronegative than iodine and will take on a charge of -1. Since the compound is neutral, the oxidation number of iodine must be +1 to balance the -1 charge of fluorine.
The oxidation number of N in NF3 is -3. Each F atom has an oxidation number of -1, and since the overall molecule is neutral, the oxidation numbers must add up to zero, making the oxidation number for N -3.
The oxidation number of KF is +1 for potassium (K) and -1 for fluorine (F). This is because alkali metals like potassium typically have an oxidation state of +1, while halogens like fluorine have an oxidation state of -1 in ionic compounds.
