Some of the elements exhibiting variable oxidation numbers are
carbon (+4, -4);
oxygen and selenium (-2 to +6);
nitrogen and phosphorus (-3 to +5)
halogens (except fluorine) (-1 to +7)
and most of the transition metals and f block elements.
No, oxidation number refers to the charge an atom would have if electrons were transferred completely, while common ions are stable charged forms of an element.oxidation numbers are a conceptual tool used to keep track of electron transfer, while common ions are stable forms observed in chemical reactions.
The oxidation state is 1.
When considered the compound as a whole, it has the oxidation number of zero. When it is considered as ions the hydrogen ions has +I and sulfate ion -II oxidation numbers. When compared with respect to elements, sulfur has +VI, hydrogen has +I and oxygen has -II as their oxidation numbers.
The oxidation number of an ion is the charge of the ion, which is determined by the number of electrons gained or lost by the atom to achieve a stable electron configuration. Positive ions have oxidation numbers that equal their charge, while negative ions have oxidation numbers that are the negative of their charge.
Transition elements usually have more than one oxidation number. In different oxidation numbers, the ions show different colors. Some of the ranges: Cu from +1 to +2; Cr from +2 to +6; Ni from +2 to +3; Co from +2 to +3 and Mn from +2 to +7.
Numbers assigned to atoms and ions to keep track of electrons are called oxidation numbers. They represent the apparent charge of an atom or ion in a compound, assuming all shared electrons are assigned to the more electronegative atom. Oxidation numbers help in balancing chemical equations and predicting the behavior of substances in reactions.
The sum of oxidation numbers in a neutral compound is always zero, as the charges balance out. In polyatomic ions, the sum of oxidation numbers equals the charge of the ion. When determining oxidation numbers, rules such as assigning elements in their elemental state an oxidation number of zero and hydrogen an oxidation number of +1 are typically followed.
the most common oxidation state of chlorine is -1.
Chlorine can have oxidation states of -1, +1, +3, +5, and +7 in various compounds. Its most common oxidation states are -1 and +1 in the form of chloride ions and hypochlorite ions.
Oxygen (in Oxide ions)
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
The chemical formula depends on the specific ions mentioned. Without knowing the ions, we cannot determine the formula or oxidation numbers. Can you provide the ions you are referring to?
