उत्तर
| \(+1.6 \times 10^{-19} \mathrm{C}\) | \(-1.6 \times 10^{-19} \mathrm{C}\) | \(+3.2 \times 10^{-19} \mathrm{C}\) |
| Proton | Electron | Alpha particle |
Explanation:
A proton has a positive charge, an electron has an equal negative charge, and a neutron has no charge. An alpha particle is a helium nucleus containing two protons, so its charge is $$+3.2 \times 10^{-19}\mathrm{C}$$.
