Phosphate in not an element, it is not the only element found in DNA, and is found in other places.
Calcium phosphate is a compound composed of calcium cations and phosphate anions. It is not an element, as elements are composed of only one type of atom.
Elements only have one kind of atom throughout. Iron phosphate has both iron and phosphorus so it isn't an element.
Phosphorus is only present in a phosphorous but not in chitin so your answer is Phosphorus :)
Carbon. Carbon.
Carbon is the primary element present in coal, making up a significant portion of its composition.
The unique element found in nucleic acids and not in other biochemicals is phosphorus. Phosphorus is a key component of the phosphate groups that make up the backbone of nucleic acids like DNA and RNA.
None.
Element b/c Molecules that contain only atoms of the same type of element are only elements. They are not compounds or mixtures because no other elements are present.
There is one atom of that element in the molecule.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
When there is no subscript on an element, it is implied that one atom of that element is present. For example, "H" would represent one atom of hydrogen.
Only if each element of one has the same value as the corresponding element in the other.
