Which subatomic particle has no charge?

## **The reasoning** Think of the atom like a carefully balanced system. **The principle here is fundamental atomic structure.** - **Electrons** carry a **negative charge** (−1) - **Protons** carry a **positive charge** (+1) - **Neutrons** are exactly what their name suggests: **neutral** — they have **no charge** (0) - **Positrons** (the antimatter twin of electrons) carry a **positive charge** (+1) Neutrons live in the nucleus alongside protons, adding mass but not affecting the atom's overall charge. This is why isotopes (same element, different neutron numbers) exist — you can change neutron count without changing chemical identity! ## **Why the wrong options tempt you** **Electron & Proton** — These are the famous pair you always hear about (positive/negative attraction), so your brain might skip over neutron as "less important." **Positron** — Sounds exotic and unfamiliar, so some students guess it thinking "maybe that's the special uncharged one?" ## **Quick takeaway** **Neutron = Neutral. No exceptions.** It's literally in the name — and it's the only subatomic particle with zero charge you'll ever encounter in these exams.
