Question 1 • 2026 Summer 305 CR_2002040-M/J Comprehensive Science 1
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.
