Phosphorus has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). It is not found free in nature, but is widely distributed in many minerals, usually as phosphates. [12] Inorganic phosphate rock, which is partially made of apatite, is today the
Phosphorus comprises 0.1% by mass of the average rock [12] (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%), [13] and consequently there are quadrillions of tons of phosphorus in Earth's 3×10 19-ton crust, [14] albeit at predominantly lower concentration than the deposits counted as reserves, which are ...
The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. [2] The remaining minerals are called " trace elements ". The generally accepted trace elements are iron , chlorine , cobalt , copper , zinc , manganese , molybdenum , iodine , selenium , [ 5 ] and bromine ; [ 6 ] there is some evidence that ...
The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.

This made early color TVs only usable indoors as bright light made it impossible to see the dim picture, while portable black-and-white TVs viewable in outdoor sunlight were already common. The composition of the phosphors changed over time, as better phosphors were developed and as environmental concerns led to lowering the content of cadmium ...
Without phosphorus, plants and animals couldn't function, so I find it troubling to read that production of the element is projected to peak in 2035, and that we are already experiencing market ...
As many know, healthy, nutrient-rich soil supports a productive vegetable garden. Nitrogen (N), phosphorus (P), and potassium (K) are the key macronutrients required by plants for their growth.
