The chemical formula is Cr2(SeO4)3.
This is the electrical charge of the ion.
An ion is an atom with a positive or negative charge.
No. The acetate ion has a -1 charge.
A molecule hasn't an electrical charge. An ion has a positive charge (cation) or a negative charge (anion).
The chromic ion is the chromium (III) ion.
The chromic ion is (CrO4)2-.
This is possible when the ion is Hydrogen chromate or HCrO4-
The chemical formula is Cr2(SeO4)3.
I like to believe that I am correct in saying... Chromous Acid. Chromite being the polyatomic ion.
Chromium (II) Carbonate. Although I'm not sure Chromium (II) can form, there might be an overall charge on your formula there...
An ion does have a charge. That is what makes it an ion.
This is the electrical charge of the ion.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
The charge of the molybdenum ion is +2.
The hydroxide ion has a 1- charge.
The bromide ion has a 1- charge.
