Practise MYP Chemistry questions on 4.3 Properties of Elements and Compounds and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
A substance that is brittle, has a high melting point, and only conducts electricity when dissolved in water is most likely a(n) __________ substance.
To melt a giant ionic lattice, __________ energy must be supplied to overcome the strong electrostatic attractions between the ions.
True or False: The strength of metallic bonding generally increases as the number of delocalized electrons per atom increases.
True or False: Pure simple molecular covalent substances, such as liquid water or molten sulfur, are generally good conductors of electricity.
True or False: While most simple molecular substances are non-conductors, some polar molecules can form ions through a reaction with water, allowing the solution to conduct.
