Which of the following represents an ion?
A particle having:
- 14 protons,
- 14 neutrons,
- 14 electrons
A particle having:
- 9 protons,
- 9 neutrons
Answer (2)
A particle with only 9 protons and no electrons would be an ion, because one proton contains a +1 charge and one electron contains a -1 charge while neutrons have no charge. This particle, without electrons would then have an ionic charge of +9.
The second particle, having 9 protons and no defined electrons, represents an ion due to an imbalance of charge. The first particle is electrically neutral with equal protons and electrons. Hence, the answer is the second particle.
