Subatomic particle with no charge:

## The reasoning An atom has three main subatomic particles. Think of them like residents in a house: - **Electrons** live in the outer shells and carry **negative charge (−1)** - **Protons** live in the nucleus and carry **positive charge (+1)** - **Neutrons** also live in the nucleus but carry **no charge (0)** — they're electrically neutral The name "neutron" itself gives you a hint: *neut-*ral. It's the only subatomic particle with zero charge, which makes it very useful in nuclear reactions because it can slip into other nuclei without being repelled by positive charges. ## Why the wrong options tempt you **A) Electron** — You might confuse "no charge" with "negative charge." But electrons definitely have charge; they're what make electricity flow! **B) Proton** — Protons are positively charged. They determine an element's atomic number. **D) Ion** — An ion isn't even a subatomic particle! It's an *atom* that has gained or lost electrons, giving it an overall charge. ## Quick takeaway **Remember: Neutrons are Neutral — both words start with 'N' and both mean zero charge.**
