What is true when an ion is formed? The atom loses one or more protons. The atom loses one or more neutrons. There is an unequal number of electrons and neutrons. There is an unequal number of electrons and protons.
Solution
When an ion is formed, there is an unequal number of electrons and protons. This is because ions are formed when atoms gain or lose electrons in order to achieve a full outer shell and become more stable. If an atom loses an electron, it becomes a positive ion (or cation). If an atom gains an electron, it becomes a negative ion (or anion). The number of protons in an atom does not change during this process, so the number of electrons and protons becomes unequal. The atom does not lose protons or neutrons when an ion is formed.
