Respuesta :
Mg²⁺ has a greater charge density than Ba²⁺.
The charge density is a measurement of the amount of electric charge present per unit of surface area, body volume, or field. How much charge is held in a specific field is determined by the charge density. It is possible to calculate charge density in terms of length, area, or volume.
Determining the movement of charge is crucial for understanding the electric field. Additionally, electric charges accumulate in such fields. Therefore, it is crucial to calculate charge density for a variety of reasons. Based on the electric object's volume and surface area, this charge density must be computed.
The Mg2+ ions are smaller than the Ba2+ ions, and have the same charge. This means that Mg2+ ions have a greater charge density.
