Why is the oxidation state of fluorine never positive?
An element exhibits a positive oxidation state when it is bonded to a more electronegative element. Fluorine is the most electronegative of all the elements. But what if fluorine bonds with extremely elecronegative oxygen and nitrogen ligands like -OCF3, -OTeF5, -OIO2F2, -N(SO2CF3)2, -N3, -N5(pentazole ligand) etc.? eg: F-OTeF5
What is the oxidation number of magnesium in MgO?
Magnesium(II) so +2
Oxygen will have a positive oxidation number when combined with?
Fluorine. Oxygen has a -2 oxidation number in all compounds except peroxides and compunds with fluorine (+1 or +2)
What is the oxidation number for F2?
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.
Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
Why is fluorine oxidation state never positive?
An atom of fluorine has the greatest attraction among all atoms for electrons; therefore, no other atom can extract an electron from a fluorine atom, as would be required for the fluorine to have a positive oxidation state.

What are the oxidation numbers of magnesium in magnesium dichromate?
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.

What elements can form a positive ion?
All elements can and many often do form positive ions.
Oxidation number of MgO?
0 in the elemental form +2 in its compounds
What are the properties of fluorine?
Fluorine is located in period 2 and group 17 in the periodic table. It is the known strongest non metal. It never gains a positive oxidation state. The corresponding acid, HF, is a weak acid. Fluorine reacts with almost all other elements and destroy many of the organic compounds forming carbon tetrafluoride and hydrogen fluoride.
Which element will never have a positive oxidation number?
Helium (He) is one such element. So is Argon (Ar). There are probably others as well.
