When are ions formed?
Understand the Problem
The question is asking about the process and conditions under which ions are formed. This typically involves the loss or gain of electrons by atoms or molecules, resulting in the creation of charged species.
Answer
Atoms lose or gain electrons to form ions.
Ions are formed when atoms lose or gain electrons to fulfill the octet rule and achieve a full outer valence electron shell. Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.
Answer for screen readers
Ions are formed when atoms lose or gain electrons to fulfill the octet rule and achieve a full outer valence electron shell. Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.
More Information
Atoms aim for a stable electron configuration, often following the octet rule of having eight electrons in their outermost shell. Cations (positive ions) form by loss of electrons, while anions (negative ions) form by gaining electrons.
Tips
A common mistake is confusing cations and anions. Remember, cations are positively charged (loss of electrons) and anions are negatively charged (gain of electrons).
