Which statements describe molecules? Check all that apply.Molecules are made of two or more atoms.Molecules are all the same sizeMolecules range in size.Molecules are only made of atoms of the same element.Molecules are only made of atoms of different elements.Molecules are made of atoms of the same element or different elements.

A molecule consists of two or more atoms chemically bonded together, so A is correct. Molecules can contain different numbers of atoms, so they range in size; C is correct. Their atoms may be from the same element, such as O₂, or from different elements, such as H₂O, so F is correct. The statements that molecules are all the same size or contain only one kind of element are too restrictive.
