Verified step by step guidance

Understand the concept of ions: Ions are atoms or molecules that have gained or lost electrons, resulting in a net electrical charge.

Differentiate between cations and anions: Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.

Focus on anions: Anions are formed when an atom gains electrons, increasing the number of negatively charged particles compared to positively charged protons.

Consider the electron configuration: When an atom gains electrons, it moves towards a more stable electron configuration, often resembling the nearest noble gas.

Remember the charge balance: The gain of electrons results in a negative charge because the number of electrons exceeds the number of protons in the atom.
