QQuestion
Give reasons for the following:
(a) Inert gases do not form ions.
(b) Covalent compounds have a low melting and boiling point.
✓Answer
(a) Inert gases have completely filled octet which makes them extremely stable. They neither lose, nor gain electrons. Hence, they do not form ions.
(b) Covalent compounds have low melting and boiling points because they have weak forces of attraction between the binding molecules, thus less energy is required to break the force of bonding.
