Understand that bonding is best described as a continuum between the ionic, covalent, and metallic models, and can be represented by a bonding triangle. Use bonding models to explain the properties of a material.
Understand the position of a compound in the bonding triangle is determined by the relative contributions of the three bonding types to the overall bond. Determine the position of a compound in the bonding triangle from electronegativity data. Predict the properties of a compound based on its position in the bonding triangle. Calculations of percentage ionic character are not required.
Define alloys as mixtures of a metal and other metals or non-metals. Explain the properties of alloys in terms of non-directional bonding, including the common examples: bronze, brass, and stainless steel.
Define polymers as large macromolecules, made from repeating subunits called monomers. Describe the common properties of plastics in terms of their structure.
Understand the formation of addition polymers. Represent the repeating unit of an addition polymer from given monomer structures.
