<span>Phosphorus is a supply that is never found as a free element
on Earth because of its high reactivity. They are mostly found in maximally
oxidized phosphorus-containing minerals as inorganic phosphate rocks. It comes
in two major forms, the white and red phosphorus. This element is essential for
life because they are part of the components of DNA, RNA, ATP, and
phospholipids that are found in cell membranes. Urine and bone ash have high
concentrates of phosphorus. It can also be used in detergents, pesticides, and
nerve agents. </span>
