* Atoms are neutral: In their natural state, atoms have an equal number of protons (positively charged particles) and electrons (negatively charged particles). This balance results in a net charge of zero, making the atom electrically neutral.
* Ions: Atoms can gain or lose electrons, becoming ions. If an atom loses electrons, it becomes a positively charged ion (cation). If it gains electrons, it becomes a negatively charged ion (anion).
In summary:
* Atoms are typically neutral.
* Ions have a positive or negative charge due to the gain or loss of electrons.
