Final answer:
Terms related to properties can be sorted into metals and non-metals: Metals include properties like density, strength, malleability, and ductility, while non-metals are associated with being brittle. The term 'conductor' can be assigned to both metals and non-metals like graphite, whereas 'appearance' needs further clarification to be sorted accurately.
Step-by-step explanation:
The provided terms can be sorted into categories of metals and non-metals based on well-known physical and chemical properties. Metals are typically shiny in appearance, malleable, ductile, and are good conductors of heat and electricity. In contrast, non-metals tend to be dull, brittle, and poor conductors of heat and electricity. Some materials, such as metalloids, can exhibit properties in between metals and non-metals, having moderate conductivity, for instance. Based on these distinctions, the correct sorting is:
- Metals: Density, Strength, Malleable, Ductile
- Non-metals: Brittle, Appearance
- Both: Conductor (as some non-metals can conduct electricity, like graphite)
- Both: Sonorous (though typically a property of metals, it is not exclusive)
The term 'Conductor' could potentially fall under both categories due to the existence of materials like graphite and metalloids that conduct electricity to various extents. 'Brittle' typically is associated with non-metals but can be considered for some metals when alloyed or under certain conditions. 'Appearance' is too vague as both metals and non-metals can have various appearances; however, if referencing the typical lustrous appearance, it could be a metal characteristic.
