What general properties do metals have?. Chapter 2 Section 2. Describing matter. Matter: anything that has mass and takes up space. Mass – the amount of matter in something. Volume – the amount of space something occupies. Which of the following is matter?. A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. Diamond. Covalent bonding. Usually gases or liquids. Covalent bonds in the molecule are strong but forces between molecules (intermolecular) are weak. Low melting and boiling points.. Due. to having w.
