Marlon Delchot answered . Metals are the elements which exhibit the highest degree of metallic behavior is known as metals, on the contrary Non-metals are such elements which do not possess any metallic behavior, and Metalloids are those elements, that possess some of the properties like metal, while some like non-metal. Metals. Metal Excess Defects. ‘X’ is carbon, ‘Y’ is diamond as it is the hardest natural substance and ‘Z’ is graphite as it is good conductor of electricity. Exist as solids and gases, exception being bromine. Metals are known for being dense and shiny and solid at room temperature, with the exception of mercury which is liquid at room temperature.
