Mg²⁺has a greater charge density than Na⁺.
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.
In comparison to sodium, magnesium has a higher charge density and a lower volume. Magnesium has a stronger metallic lattice and a higher melting point than sodium because it has a larger charge density.
