positive
In ionic chlorine compounds, the ionic charge of chlorine is -1.
Selenium typically has an ionic charge of -2 when forming compounds.
Oxide ions have a charge of -2.
Generally -3 in its compounds (as in nitrides)
The total charge of an ionic compound is always neutral, meaning that the positive charge of the cations balances out the negative charge of the anions. This is because ionic compounds are formed through the transfer of electrons from one element to another.
ionic compounds are polar compounds because they have charge separation between them
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
Ionic compounds are typically made up of a metal cation and a non-metal anion. The metal cation provides the positive charge, while the non-metal anion provides the negative charge. So, while not all ionic compounds contain a metal, they often do.
Ionic compounds are compounds composed of ions held together by electrostatic forces. These compounds typically consist of a positively charged metal ion and a negatively charged nonmetal ion. The metal ion carries a positive charge, while the nonmetal ion carries a negative charge.
+3 is Boron's overall charge. Boron's ionic charge is +5.
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
Sodium is Na; ionic compounds of sodium contain Na+
