- CO2, in the air is a rare trace gas, makes up only 0,03% by volume of the Earth's atmosphere.
- The atmospheric CO2 concentration has risen strongly since about 1850, from 280 ppm (a value typical for warm periods during at least the past 700,000 years) to over 380 ppm.
- As of November 2011, carbon dioxide in the Earth's atmosphere is at a concentration of 390 ppm by volume.
- CO2 was five hundred million years ago 20 times more prevalent than today
- CO2 is non toxic in lower concentrations: typical less than 1% (10,000 ppm).
- CO2 is soluble in water, in which it reversibly converts to H2CO3 (carbonic acid)
- CO2 is colorless and odorless at low concentrations
- CO2 is a food additive used as a propellant and acidity regulator in the food industry. It is approved for usage in the EU (listed as E number E290), by the oil industry, and the chemical industry.
- CO2 is one of the most commonly used compressed gases for pneumatic (pressurized gas) systems in portable pressure tools.
- Up to 40% of the gas emitted by some volcanoes during sub aerial eruptions is CO2.
- Adaptation to increased levels of CO2 occurs in humans.
- The body produces approximately 2.3 pounds (1 kg) of carbon dioxide per day per person.

MLA Citation:webelements.com, Oxygen: The Essentials, http://www.webelements.com/oxygen/
- about one fifth of the atmosphere is oxygen gas,
- oxygen is the third most abundant element found in the sun, and it plays a part in the carbon-nitrogen cycle, one process responsible for stellar energy production
- About two thirds of the human body, and nine tenths of water, is oxygen
- The gas is colourless, odourless, and tasteless.
- Oxygen was discovered by Joseph Priestley, Carl Scheele at 1774 in England, Sweden.
- there is not normally any need to make oxygen in the laboratory as it is readily available
- Oxygen in excited states is responsible for the bright red and yellow-green colours of the aurora.
- It is essential for all life
- Liquid and solid oxygen are pale blue and strongly paramagnetic
