Geocache Description:

One of the caches in the ChemCache VIA: Chalcogens (GCWJEM) Series. Get the code to solve the puzzle!

This is another one of the Chem Caches - This one is part of the unknown cache ChemCache VIA: Chalcogens. Often called the Oxygen group, this is the technical name for the 16th column of the periodic table. Oxygen is a Group 16 element. While about one fifth of the atmosphere is oxygen gas, the atmosphere of Mars contains only about 0.15% oxygen. 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. Oxygen in excited states is responsible for the bright red and yellow-green colours of the aurora. About two thirds of the human body, and nine tenths of water, is oxygen. The gas is colourless, odourless, and tasteless. Liquid and solid oxygen are pale blue (see picture above) and strongly paramagnetic (contains unpaired electrons). [from www.webelements.com]
