In general, electrons can move within positive ions. An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net positive or negative charge, respectively. When an atom loses one or more electrons, it becomes a positively charged ion, also known as a cation.
Within a positive ion or cation, the number of protons in the nucleus is greater than the number of electrons, resulting in an overall positive charge. The remaining electrons within the ion are still attracted to the positively charged nucleus and can move within the ion's atomic structure.
However, it's important to note that the movement of electrons within positive ions is influenced by the specific atomic and molecular properties of the ion, such as its electronic configuration, energy levels, and bonding. The behavior and mobility of electrons within ions are governed by the principles of quantum mechanics and the interactions between the charged particles within the ion.
In certain cases, such as in ionic crystals or in ionized gases, electrons within positive ions can participate in electrical conductivity and contribute to the overall behavior of the material or system.
