Essential Chemistry for IGCSE - Structure And Bonding (Section 1 - No. 44)
Why are simple molecular substances gases or liquids at room temperature?
They have strong intermolecular forces.
The covalent bonds are easily broken.
They have weak intermolecular forces.
The atoms are easily ionized.
توضیح
Simple molecular substances have weak intermolecular forces. This allows the molecules to move apart easily and makes them a liquid or a gas at room temperature.
