Final answer:
Malleability and ductility are properties of metals, while the purple color is a property of bromine.
Step-by-step explanation:
Malleability and ductility are properties of metals. Malleability refers to the ability of a metal to be shaped or formed into thin sheets, while ductility refers to its ability to be drawn into thin wires. For example, metals like gold and silver are malleable and ductile.
Similarly, bromine is a red-brown liquid at room temperature, but when it is cooled to -7.2 degrees Celsius, it forms purple-black crystals. These crystals are known as the purple color of bromine. So, the relationship between the first two words and the other one is that malleability is a property of metals, and purple color is a property of bromine.
