Phosphate in not an element, it is not the only element found in DNA, and is found in other places.
Elements only have one kind of atom throughout. Iron phosphate has both iron and phosphorus so it isn't an element.
carbon
Carbon. Carbon.
The only element that is not found in any of the 20 essential amino acids but is found in nucleic acids is Phosphorus. It is found in the "Sugar-Phosphate backbone" of nucleic acid but is not found in any of the essential amino acids. Many proteins interact with phosphate groups but they do not make up the protein.
Phosphorus is only present in a phosphorous but not in chitin so your answer is Phosphorus :)
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.
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.

Balmer series just represents the visible radiations region and it is present in the spectra of every element. It is just the case that we study only hydrogen atom.
Only if each element of one has the same value as the corresponding element in the other.
Carbon is the main element in diamonds because it forms covalent bonds and a crystal lattice which is long chains of carbons that in turn form a very strong bond.
