Answer

Brief Explanations:

Mercury is an element on the periodic table. Elements are pure substances as they consist of only one type of atom. Liquid mercury is just the elemental form of mercury in the liquid - state and not a compound (which is made of different elements chemically combined), nor an impure substance. It is relatively unreactive under normal conditions compared to some other elements, but this is not the key characteristic for classification here. The main point is that it is a pure substance and an element.

Answer:

a pure substance and an element
