Show the formation of `Na_(2)O` and MgO by the transfer of electrons.

Explanation

To show the formation of Na₂O (sodium oxide) and MgO (magnesium oxide) by the transfer of electrons, we can break down the process into clear steps for each compound.

### Formation of Na₂O

1. **Identify the Elements**: Sodium (Na) and Oxygen (O).
2. **Determine Valence Electrons**: Sodium has 1 valence electron, and oxygen has 6 valence electrons.
3. **Electron Transfer Requirement**: Oxygen needs 2 electrons to complete its octet (8 electrons in its outer shell). Therefore, 2 sodium atoms will be required to donate their electrons.
4. **Electron Donation**: Each sodium atom donates its 1 valence electron to the oxygen atom. This results in:
