Which of the following elements makes up 8% of our body weight and 70% of Earth's crust?

Oxygen is often referred to as the universal life force or element of 'life'. Like all elements, oxygen has multiple allotropes at different temperatures. Earth materials are oxidized forms of oxygen; the most common form, ordinary (or atomic) oxygen, is a greenish-blue gas with a faint golden tinge.
