Is it true that in ionic compounds the oxidation number is the same as the charge on the ion . a neutral ionic compound can only contain ions with identical charges?
No, it is not true that a neutral ionic compound can only contain ions with identical charges. You can have, for example, a compound that consists of twice as many positive ions as negative ions, but the positive ions have only half the charge; +1 ions bonded to -2 ions. There are many different possible ratios with which different elements or radicals combine. As long as the total amount of charge adds up to zero, you still have a neutral ionic compound.
What is the oxidation number of halide ions?
Fluorine: -1 Chlorine: -1, +1, +3, +5, +7 Bromine: -1, +1, +3, +5, +7 Iodine: -1, +1, +3, +5, +7 The normal oxidation state of halides is -1, but with, for example, chlorine other oxidation states exist. Hypochlorites (+1), Chlorites (+3), Chlorates (+5), Perchlorates (+7). The same is true for all halogens, with the exception of fluorine, that seems to like it's -1 status and won't form fluorates.
Did cl change oxidation number tue or false?
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
What is true about the sum of all oxidation numbers?
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
What is the oxidation number for S in S 2?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.Atomic sulfur has oxidation number of 0. Its simple ion, sulfide carries oxidation status -2. While forming numerous compounds, the oxidation number of sulfur can vary form -2 to +6.
What is true of the oxidation number?
It is an integer.
Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
What is the oxidation number of carbon in strontium carbonate?
In the carbonate CO32- the sum of the oxidation numbers is the ionic charge (true for all poyatomic ions) O is assigned -2 so C has +4. (maths 4 +(-6) = -2)

How do you calculate protons and in ions?
The protons are always the same as their matching atomic number. This is also true of ions. Protons never change.
What is the oxidation number of Sn in element form?
Zero. This is true for all elements inn their elemental form.
What is the oxidation number for S in S 2?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.Atomic sulfur has oxidation number of 0. Its simple ion, sulfide carries oxidation status -2. While forming numerous compounds, the oxidation number of sulfur can vary form -2 to +6.
How is charge related to oxidation number?
Charge refers to the electrical charge of an ion, which is the number of valence electrons gained or lost by an atom. Oxidation number, on the other hand, is a hypothetical charge assigned to an atom in a compound based on a set of rules. The oxidation number can be used to determine the charge of an ion in a compound, but it does not always represent the true charge of the atom.
What is the oxidation state of h in H 2 g?
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
