Oxidation number is the charge per atom in a compound.
Cl2= 2- (Cl= 1-)
Cu would have to be 2+ to balance the compound, because there is only one copper atom.
K[CuCl2]
+2 oxidation state for the Copper. -1 for the Chloride
Copper can exist in two states of oxidation.The oxidation state of Cu in CuCl2 (cupric chloride) is +2 and that of Cl- is -1.However,the oxidation state of Cu in CuCl (cuprous chloride) is +1 and that of Cl- is -1.
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
oxidation number of I is -1. oxidation number of F is +1.
K[CuCl2]
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
+2 oxidation state for the Copper. -1 for the Chloride

oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The Roman numeral following the cation tells you the oxidation number of that cation. For example, Cu(ll)chloride tags you it is CuCl2 because the (ll) after Cu indicates an ox. no. of 2+.
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
Zn has oxidation number +2; S has oxidation number -2
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number for H is +1, and the oxidation number for O is -1.
