which event would be impossible to explain by using john daltons model of the atom? an iron atom emits particles when it is struck by light. an oxygen atom combines with two hydrogen atoms to form water. an acid reacts with a base to form salt and water. the atoms in sodium metal react with water.
Answer
Brief Explanations:
John Dalton's model considered atoms as indivisible solid spheres. The photoelectric effect (an iron atom emitting particles when struck by light) involves the emission of electrons from an atom, which cannot be explained by an indivisible - atom model. Dalton's model could explain simple chemical reactions like combination of atoms to form compounds (oxygen and hydrogen forming water), acid - base reactions, and metal - water reactions as they involve rearrangement of atoms. But the emission of particles from an atom due to light requires the concept of sub - atomic particles (electrons), which was not part of Dalton's model.
Answer:
An iron atom emits particles when it is struck by light.
