The most abundant compounds in the earths atmosphere are water vapor and?
The most abundant compounds in Earth's atmosphere are nitrogen and oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen comprises about 21%. Water vapor concentrations vary, but are typically around 1-4% of the atmosphere.
Facts about the element oxygen?
is the element with atomic number 8 and represented by the symbol O.Because it comprises most of the mass in water, oxygen comprises most of the mass of living organisms (for example, about two-thirds of the human body's mass)Oxygen is a member of the chalcoqen groupof the periodic table.

Percentage of oxygen in air?
Oxygen comprises about 21% of fresh air. Room air is nearly always refreshed from outsides sources sufficiently fast for this value to hold true. However, if ventilation is extremely poor it can differ.
What is the percentage of aluminum in the Earth's crust?
Aluminum makes up about 8% of the Earth's crust by weight, making it the third most abundant element in the Earth's crust after oxygen and silicon.
What element is the second most abundant in the body?
Most of our body is made up of water (H20); therefore hydrogen is the most abundant (i.e. numerous) element and oxygen is the second most abundant. However, since oxygen is much heavier than hydrogen, it comprises a larger percentage of body weight (about 65%) than does hydrogen (about 10%).
Which component of mammalian blood is most directly involved in the transport of oxygen?
Iron found as part of hemoglobin which comprises most of each red blood cell (RBC).
