If I absolutely had to answer with two atoms, I'd say carbon and hydrogen. This is because carbon is the absolutely indispensible atom that is the absolute basis of all organic molecules, forms they're backbones, and it is carbon's ability to make multible chemical bonds that allows for complex molecular structures. Secondly, hydrogen because any time a carbon molecule has a free chemical bond (not bound to another carbon or some other atom), it bonds to hydrogen. Hydrocarbons are entirely carbon and hydrogen.
I must say however that for some organic molecules (e.g. carbohydrates) I would have to say there are three atoms which are the basis: carbon, hydrogen, and oxygen.
Amino acids are organic molecules that contain two or more atoms, specifically carbon, hydrogen, oxygen, and nitrogen. Amino acids are the building blocks of proteins and are essential for various biological processes in living organisms.
Atoms are the building blocks of molecules. Molecules are formed when two or more atoms chemically bond together. Different combinations of atoms can create a wide variety of molecules with unique properties.
Molecules can be made up of any number of atoms, ranging from just two atoms (such as in a molecule of hydrogen gas, H2) to many thousands of atoms (like in complex organic molecules). The number of atoms in a molecule depends on the chemical formula of the substance.
Two molecules of ammonia contain 6 hydrogen atoms.
Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
Two or more.
an organic molecule is any molecule that contains carbon atoms in a covalent bond where two or more atoms share electrons.
Amino acids are organic molecules that contain two or more atoms, specifically carbon, hydrogen, oxygen, and nitrogen. Amino acids are the building blocks of proteins and are essential for various biological processes in living organisms.
Organic molecules all contain carbon and hydrogen atoms. In addition to these two elements, most organic molecules also contain oxygen and nitrogen atoms. Other elements such as phosphorus and sulfur may also be present in smaller quantities.
Atoms. Molecules are two or more atoms together.
