Atomic Theory & Scientists 1. Write the letter of each sentence that is true about Dalton's atomic theory. a. All elements are composed of tiny, indivisible particles called atoms. An element is composed of several types of atoms. b. c. Atoms of different elements can physically mix together, or can chemically combine in simple, whole-number ratios to form compounds. d. Chemical reactions occur when atoms are separated, joined or rearranged; however, atoms of one element are never changed into atoms of another element by a chemical reaction.

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.
