 Pauling's principle of electroneutrality

Pauling's principle of electroneutrality states that in a stable ionic or molecular system, the total positive charge must balance the total negative charge. This principle is particularly important in the context of crystallography and the structure of minerals, as it helps explain how different ions combine to form stable compounds while maintaining charge balance. Essentially, Pauling's principle emphasizes that in any system, there cannot be an excess of positive or negative charge.
