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.
What else can I help you with?
Which organic molecule contains two or more atoms?
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.
How are atoms and molocules related?
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 are made of how many atoms?
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.
If two atoms of nitrogen completely react with six atoms of hydrogen to form two molecules of ammonia which best describes the number of hydrogen atoms present in the two molecules of ammonia?
Two molecules of ammonia contain 6 hydrogen atoms.
How many carbon atoms in two ethene molecules?
Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
How many atoms do organic molecules have?
Two or more.
How are organic molecules made?
an organic molecule is any molecule that contains carbon atoms in a covalent bond where two or more atoms share electrons.
Which organic molecule contains two or more atoms?
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.
What elements make up all organic molecules?
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.
Do elements consist of atoms or molecules?
Atoms. Molecules are two or more atoms together.

What are the total number of atoms in two oxygen molecules?
There are 4 oxygen atoms in two oxygen molecules.
If two atoms of nitrogen completely react with six atoms of hydrogen to form two molecules of ammonia which best describes the number of hydrogen atoms present in the two molecules of ammonia?
Two molecules of ammonia contain 6 hydrogen atoms.
How many atoms of hydrogen are in two molecules of benzene?
Two atoms.
What are molecules made up of?
Molecules are substances consisting two or more atoms.
How many carbon atoms in two ethene molecules?
Four: 2x2 = 4 C atoms in 2C2H4 (= two molecules C2H4)
