Solution

(i) The electron-dot structure of KCl is:

In KCl, the potassium atom transfers its 1 electron to the chlorine atom to form an ionic bond.

(ii) The electron-dot structure of NH₃ is:

In NH₃, each hydrogen atom shares its one electron with the nitrogen atom to form a covalent bond.

(iii) The electron-dot structure of CaO is:

In CaO, the calcium atom transfers its two electrons to the oxygen atom to form an ionic bond.

(iv) Electron-dot structure of N₂ is

In N₂, one nitrogen atom shares its three electrons with another nitrogen atom to form a covalent bond.

(v) The electron-dot structure of CaCl₂ is:

In CaCl₂, one calcium atom transfers its two electrons to the two chlorine atoms to form an ionic bond.
