Organic compounds always contain hydrocarbons (carbon & hydrogen); any other elements in the compound (e.g. oxygen or nitrogen) form the functional group, which is the reactive part of the compound & defines the compounds name.The definition of Organic Chemistry is the chemistry of the compounds of Carbon. This indicates that the most prevalent element in organic compounds is Carbon, yet it is closely bonded with Hydrogen, Oxygen, Nitrogen and Phosphorus, to name but a few.An organic compound is a molecule that contains at least 1 carbon.Atoms. (The answer "carbon" is not necessarily true; carbon tetrachloride is a counterexample.)
uranium, caesium, potassium, beryllium, etc.
H2SO4==sulfuric acid HCL==hydrochloric acid H2SO3==sulfurous acid NOTE: The common factor for all three is that they lead off with H, the hydrogen element. Then too there are the organic amino acids, of which there are twenty different ones that have the general formula R-CH(NH2)-COOH. R stands for a functional group of elements that always contains at least one H element.
Francium is the least electronegative element
Helium and Neon - neither react in their own right so with each other is impossible.
