Solution

Answer :

(i) The electron-dot structure of $C O_{2}$ is:

Both oxygen and carbon share their two electrons to form a covalent bond in carbon dioxide, $C O_{2}$ .

(ii) The electron-dot structure of $M g O$ is:

Magnesium donates its two electrons to the oxygen atom to form an ionic bond in magnesium oxide, $M g O$

(iii) The electron-dot structure of $H_{2} O$ is:

The oxygen atom shares its one electron with each hydrogen atom to form a covalent bond in the water molecule.

(iv) The electron-dot structure of $H C I$ is:

The hydrogen atom shares its one electron with a chlorine atom to form a covalent bond.

(v) The electron-dot structure of $M g C l_{2}$ is:

The magnesium atom transfers its one electron to each chlorine atom to form an ionic bond.
