Quizplus · Accepted Answer

The discovery of the element gallium was not in conflict with Dalton's atomic theory as it was explained by the theory. Dalton's theory explained that elements were made up of atoms, all atoms of the same element had identical properties, and atoms of different elements had different properties. Therefore, the discovery of a new element like gallium did not contradict the theory. However, discoveries related to electrical charge, electrons, and protons challenged the basic assumptions of Dalton's atomic theory, leading to modifications of the theory over time.
