प्रश्न
An atom changes to a charged particle called ion if it loses or gains electrons. The charge on an ion is the charge on electrons plus charge on protons. Now, write the missing information in the table given below:
| Name of Ion | Proton Charge | Electron Charge | Ion Charge |
| Hydroxide ion | +9 | – | –1 |
| Sodium ion | +11 | – | +1 |
| Aluminium ion | +13 | –10 | – |
| Oxide ion | +8 | –10 | – |

उत्तर
Hydroxide ion charge = Proton charge + Electron charge
`\implies` –1 = +9 + Electron charge
`\implies` Electron charge = –1 – 9 = –10
Sodium ion charge = Proton charge + Electron charge
`\implies` +1 = +11 + Electron charge
`\implies` Electron charge = +1 – 11 = –10
Aluminium ion charge = Proton charge + Electron charge
`\implies` +13 + (–10) = +13 – 10 = +3
Oxide ion charge = Proton charge + Electron charge
`\implies` +8 + (–10) = +8 – 10 = –2
