Left: American plant physiologist Frank Thone's 1936 depiction of a plant as a "CHNOPS plus" system, i.e. he described plant systems as systems comprised of the elements: carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur (CHNOPS) plus potassium and calcium, among others. This is chemical upgrade to older late 18th century, albeit now-defunct (2009), term "biological system" (see: bio-). [1] Right: a 2010 high school level rendition of the CHNOPS model by American illustrator and former high school biology teacher Katie McKissick from her blog article “That Which Life is Made of, Dude”, in which she explains: “At the most basic level, we are made of atoms, just like all matter is. Living things are mainly composed of the following ingredients: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.” [2] |
1. For carbon-containing compounds, carbon (C) appears first.2. Carbon is followed immediately by hydrogen (H), if present.3. Compounds are listed by increasing number of atoms.4. All non-carbon element symbols follow in alphabetical order, and within alphabetical order are listed by increasing atom count.
“I am made from the C-H-N-O-S-P combination from which a Bunsen, Helmholtz, Kirchhoff came.”

"But a biochemistry could emerge in which life is powered by the * This small group of low molecular-weight 'core elements of life' has been dubbed the 'CHNOPS System' by Armstrong, et al. (1964)."
Further refined calculations, however, began to give way to the view that the old Hill order system (alphabetical) was an an inconsistent way of ordering atoms, particularly when dealing with a 26 atoms in one molecular formula. The new system, outlined below, lists atoms via decreasing atomic count in the molecule.

“Six chemical elements are essential parts of protoplasm, the living substance itself. These are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulphur. Their initial letters, which happen also to be their chemical symbols, have been arranged into a memory-saver word or mnemonic: CHNOPS — pronounced like the German word for strong liquor, Schnapps. There is a considerable quantity of the first four elements in protoplasm, and only a very little of the other two; but those small amounts are indispensable to life. Take them away, and protoplasm is no longer protoplasm; neither is it any longer alive.” ”

The new system model is depicted well by the 1993 “cell-as-molecule” approach, pioneered by English physical chemist Lionel Harrison, and the 2002 “human-as-molecule” (human molecule) approach, pioneered by American limnologists Robert Sterner and James Elser, according to which organisms are defined as individual abstract molecules, each defined by a characteristic molecular formula: 22-elements according to the Sterner-Elser human molecular formula (2002):
or 26-elements according to the Thims human molecular formula (2007); a view according to which the old 6-element CHNOPS model becomes obsolete, archaic in a sense. |

“Here, as elsewhere, evolution may have proceeded partly by the loss of function and capacity, and the so-called bioelements, C H N O P S Na K Ca Fe etc., with which present-day organisms unenterprisingly carry out 99.99 per cent, of their activities, may have been economically selected from an initially more catholic approach to chemistry.”— Author (1954), “Article”, New Biology, 16-17
“There is no evidence of a special life force, all of life on earth, including ourselves, is based on chemical processes and the four most common elements involved in the chemistry of life are hydrogen, carbon, oxygen and nitrogen, collectively known by the acronym CHON. We are made out of exactly the raw materials which are most easily available in the universe. The implication is that the earth is not a special place, and that life forms based on CHON are likely to be found across the universe, not just in our galaxy but in others. It is the ultimate removal of humankind from any special place in the cosmos, the completion of the process that began with Copernicus and De Revolutionibus.”— John Gribbin (2002), “CHON and Humankind’s Place in the Universe” [10]
