no cations have a positive charge.
The charge of sulfate ions is 2-.
The charge of nitrate ions is -1.
On their own metals have no charge. Metal ions have a positive charge.
The ionic charge of chloride ions is -1.
This compound is of course neutral.
A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of the ions
Hydrogen ions are H+Hydroxide ions are OH-neutrons are written n and have no chargeelectrons are written e- and have a negative charge.So only hydrogen ions, H+, has a positive charge.
Hydronium Ions
Plus charge, ie, it has H3O^+ ions (hydronium ions)
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
The charge on the Sc ions in Sc2O3 is 3+. This can be determined by recognizing that oxide ions always have a charge of 2-, and there are three of them, so the total oxide charge is 6-. There are two scandium ions, and since the compound must be neutral, the total charge on the two scandium ions has to be 6+, so the charge on each scandium ion is 3+.
It would have a charge of -1 in water, the charge would be negative.A fluoride ions has a charge of -1. Symbol: F-(B.t.w. 'Fouride Ions' as spelled in the original question is chemically unknown)
