The most common oxidation state of chlorine is -1, where it exists as chloride ions (Cl-).
The most common oxidation number of oxygen in compounds is -2. This means that in most compounds oxygen will have an oxidation state of -2.
The most common oxidation state of zirconium is +4. Zirconium readily forms the Zr4+ ion by losing four electrons.
The oxidation state of platinum (Pt) is usually +2 or +4. In some less common cases, platinum can also exhibit oxidation states of +0 and +6.
The most common oxidation number for nickel is +2. Nickel is a transition metal that can also exhibit oxidation states of +1, +3, and +4, but the +2 oxidation state is the most stable and commonly observed.
-1, 0, 1, 3 and 5 oxidation states The most common is 0 (its unreacted state)
The most common oxidation state of chlorine is -1, where it exists as chloride ions (Cl-).
There are no such metals whose common oxidation state is -2
The oxidation state is 1.
Mercury's most common oxidation state is +2
The most common oxidation number of oxygen in compounds is -2. This means that in most compounds oxygen will have an oxidation state of -2.
Like most metals, gold loses electrons when forming compounds. It also depends on the oxidation state. +1 or +3 are most common.
The most common are 0 and 3+.
+4 is the most common
oxygen
The most common oxidation state of zirconium is +4. Zirconium readily forms the Zr4+ ion by losing four electrons.
The oxidation state of platinum (Pt) is usually +2 or +4. In some less common cases, platinum can also exhibit oxidation states of +0 and +6.
