An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
No They are ions made up of more than one atom and acts as a single unit.
No.
CuO is made up of Cu2+ and O2- ions. So there are two ions, per molecule of CuO.
MgCl2 (Magnesium Chloride)
No
Yes. It is made up of Na+ ions and Cl- ions.
Ions made up of more than one atom are called polyatomic ions.
Salts are made of metal ions and nonmetal ions.
polyatomic ions
No They are ions made up of more than one atom and acts as a single unit.
Ions may be components of a molecule.
Polyatomic ions.
Na2S.
No.
CuO is made up of Cu2+ and O2- ions. So there are two ions, per molecule of CuO.
Copper carbide is a salt. As the element implies, the ions present are copper ions and carbide ions. Carbide ions are made of carbon atoms.
