Write two distinct integers whose sum is equal to one of the integers.
An atom consists of charged particles called electrons and protons. Each proton has a charge of +1 and each electron has a charge of –1. Remember number of electrons is equal to number of protons, while answering these questions:
- What is the charge on an atom?
- What will be the charge on an atom if it loses an electron?
- What will be the charge on an atom if it gains an electron?
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 | – |
