A cartogram depicting the abundance of elements in the earth's crust. This shows up best using the "Bar chart" option on the chart. Notice the "sawtooth" effect where elements with even atomic numbers tend to be more strongly represented than those with odd atomic numbers. The chart above shows the log of the abundance (on a parts per billion scale) of the elements by atom number in our sun.

Free Gift for you: Interactive Periodic Table Let me tell you how this Interactive Periodic Table will help you in your studies. As such, it readily forms compounds (notably. The elements whose atomic masses are written in bracket ( ) are the synthetic elements and their atomic masses values represent the Atomic Mass of the most stable isotope. Image showing periodicity of the logarithm of the abundance (by atom rather than weight) in the sun of the chemical elements as a heat map on a periodic table grid. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. Image showing periodicity of the logarithm of the abundance in the earth's crust of the chemical elements as a heat map on a periodic table grid. Use the links in the location column for definitions, literature sources, and visual representations in many different styles (one of which is shown below) Location Local concentrations of any element can vary from those given here an orders of magnitude or so and values in various literature sources for less common elements do seem to vary considerably.Ībundances for oxygen in a number of different environments. oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table. Values for abundances are difficult to determine with certainty, so all values should be treated with some caution, especially so for the less common elements. In this table of abundances, values are given in units of ppb (parts per billion 1 billion = 10 9), both in terms of weight and in terms of numbers of atoms. Abundances of oxygen in various environments The atmosphere of Mars contains about 0.15% oxygen. Oxygen is the third most abundant element found in the sun, and is involved in the carbon-nitrogen cycle, one of the processes responsible for stellar energy production. It is present in any number of minerals and makes up most of the weight of water. It is the most abundant element in the earth's crust (followed by silicon). Oxygen gas (dioxygen, O 2) makes up 21% of the atmosphere by volume.
