Multiple Choice

Can a single atom be considered a molecule?

No, because a molecule consists of two or more atoms bonded together.

No, because molecules are defined by their chemical properties.

Yes, because atoms are the building blocks of molecules.

Yes, because atoms can exist independently as molecules.

Verified step by step guidance

Understand the definition of a molecule: A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Consider the definition of an atom: An atom is the smallest unit of an element that retains the chemical properties of that element. Atoms are the building blocks of molecules.

Evaluate the statement 'Can a single atom be considered a molecule?': A single atom does not meet the definition of a molecule because it is not composed of two or more atoms bonded together.

Analyze the options given: The correct answer should align with the definition of a molecule, which requires multiple atoms bonded together.

Conclude that a single atom cannot be considered a molecule because it does not fulfill the requirement of being composed of two or more atoms bonded together.
