Explain why the charge on a simple ion is linked to electron loss or electron gain.

In the subtopic Ionic bonding, this learning objective focuses on explain why the charge on a simple ion is linked to electron loss or electron gain. Within Chemical bonds, ionic, covalent and metallic, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include charge, simple, linked, electron, and loss. simple ion means an ion formed when an atom loses or gains electrons, resulting in a net charge. Avoid students often confuse the charge of a simple ion with the number of electrons lost or gained, thinking that the charge is simply the number of electrons involved; instead emphasize that the charge on a simple ion is determined by the loss of electrons for positive ions and the gain of electrons for negative ions, and that it reflects the difference between protons and electrons. For exam answers, remember that the charge on a simple ion is determined by the number of electrons lost or gained during the formation of the ion.
