Final answer:
The incorrect statement is that oxygen is a metal. Oxygen is actually a non-metal and, along with hydrogen, makes up water (H2O), a polar compound essential for life and known for temperature stabilization properties.
Step-by-step explanation:
The incorrect statement from the options provided is: d) Oxygen is a metal.
Oxygen is not a metal; it is a non-metallic chemical element that is essential for the survival of living organisms as part of water (H2O) and necessary for combustion and respiration processes.
Water, represented chemically by [H2O], is a polar compound made up of hydrogen and oxygen in a fixed ratio and is known for its unique properties such as its ability to stabilize temperature and its essential role in supporting life.
Hydrogen, correctly described as a molecule (H2), is a gas under standard conditions and typically exists as diatomic molecules.
