Therefore, water is a compound and not a mixture and it is made up of identical molecules which are bonded together.Is water classified as an element compound or mixture *?
Water is a compound because it contains two different atoms (hydrogen and oxygen) chemically bonded together.- Water ( H 2 O ) is a compound because: Water is made up of two elements combined chemically i.e.; Hydrogen and Oxygen having a fixed composition of 2:1 where 2 atoms of hydrogen have combined with 1 atom of oxygen or 1:8 by mass. The properties of the water are different from its elements i.e.; hydrogen and oxygen.
