- Oxygen and sulfur are the two most important members of this family of elements. Oxygen makes up about 20% of the air. Oxygen is found in so many natural compounds that it is the most abundant element in the earth's crust. Oxygen is commercially obtained from the fractional distillation of liquefied air.

- 26. Trace. 5. Trace. The percentages are percent by mass of the indicated elements. The composition of the human body is seen to be distinctly different from the abundance of the elements in the Earth's crust.The elements upon which life is based are often summarized by the combination CHONPS, carbon, hydrogen, oxygen, nitrogen, phosphorous and sulfur.ll others. 1.5. Given the abundance of oxygen and silicon in the crust, it should not be surprising that the most abundant minerals in the earth's crust are the silicates. Although the Earth's material must have had the same composition as the Sun originally, the present composition of the Sun is quite different.

Oxygen Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass. Oxygen is an important part of the atmosphere, and is necessary to sustain most terrestrial life as it is used in respiration.y mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standardized conditions for temperature and pressure, two atoms of the element bind to form dioxygen, a diatomic gas that is colorless, odorless, and tasteless, with the formula O 2.

Carbon Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all forms of carbon-based life, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen.arbon is the fourth most abundant chemical element in the universe by mass after hydrogen, helium, and oxygen. Carbon is abundant in the Sun, stars, comets, and in the atmospheres of most planets.
