Hydrogen: 1
Oxygen: 2
Nitrogen:3
Carbon: 4
The following four elements make up 90 percent of the mass of living things: Oxygen - 65% Carbon - 18.5% Hydrogen - 9.5% Nitrogen - 3.2%
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
Generally these elements form covalent bonds.
Protein contains nitrogen, carbon, oxygen, and hydrogen
carbohydrates
Carbon, Hydrogen, Nitrogen, Oxygen
Carbon will form four covalent bonds, nitrogen will form three covalent bonds, oxygen will form two covalent bonds, and hydrogen will form one covalent bond. Click on the related link to see a diagram showing the structure of an amino acid.

the main elements in nucleic acid are carbon,hydrogen,oxygen,nitrogen and phosphorus. carbon,hydrogen,oxygen,nitrogen and phosporus are the main elements of nucleic acid.
Oxygen is the most abundant element in the human body, followed by Carbon, Hydrogen and Nitrogen. Calcium is abundant, as well.
Oxygen forms lots of covalent bonds, typically with carbon, hydrogen, nitrogen, or chlorine, or with other oxygen atoms in the case of the diatomic oxygen molecule.
