Formation of Negative Ions (Anions) Conversely, an atom gains a negative charge by becoming an anion, which occurs when it gains one or more electrons. This loss reduces the negative charge in the electron cloud, leaving the stronger positive charge of the protons in the nucleus unopposed.
Materials Science Applications Of Charged Atoms
Chemical Bonding and Stability The primary driver for an atom to gain or lose charge is the pursuit of stability. For instance, a sodium atom readily loses a single electron to achieve a stable electron configuration, transforming into a positively charged sodium ion (Na⁺).
Atoms strive to achieve a full outer electron shell, a state that mirrors the electron configuration of noble gases. Ions interact strongly with polar solvents like water, a process essential for biological functions and industrial applications.

This attraction forms ionic bonds, the basis for compounds like table salt (sodium chloride), where the positive sodium ions and negative chloride ions lock into a rigid crystal lattice. A chlorine atom, for example, gains an electron to fill its valence shell, becoming a negatively charged chloride ion (Cl⁻).
