When a neutral atom gains or loses electrons, it becomes charged and is called a

Conclusión. Los cationes son iones con carga positiva que se forman cuando los átomos neutros pierden electrones; los aniones son iones con carga negativa que se forman cuando átomos neutros ganan electrones.

Explanation:

the answer is b. dilution

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
