The chunk of sodium has a mass (in kilograms) equal to the atomic number of fluorine. A tremendous explosion follows emitting light and heat able to be observed from a drone flying at an altitude of approximately 53 m. How many atoms of sodium from the original chunk remain in Wisconsin after the reaction is complete? This is an MCAT style question.
