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+.
No, Sc2O3 is an ionic compound, not a molecular compound. It is composed of scandium ions (Sc3+) and oxide ions (O2-), which are held together by ionic bonds.
Sc2O3 is an ionic compound. It is composed of Scandium (Sc) which is a metal, and Oxygen (O) which is a non-metal. In ionic compounds, metals donate electrons to non-metals to form charged ions that are held together by electrostatic forces.
Scandium has the chemical symbol Sc and 21 is it's atomic number. A link is provided to the Wikipedia article on this (usually considered) rare earth element.
The charge of sulfate ions is 2-.
The charge of nitrate ions is -1.

Sc2O3
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.
