Identify the FALSE statement. Stellar nucleosynthesis:
is the term for the process by which stars create the heavier elements. means stars use their small atoms to produce larger atoms. is a normal process that happens during the life cycle of stars. reactions vary and are dependent on the mass of the star. produces elements up to atomic number 26 (iron) in low-mass stars like our Sun.
