What are three main ideas in Dalton's atomic theory? Check all that apply. Atoms combine to form compounds in simple, whole number ratios. Most of the atom's mass and all of its positive charge are contained in a small core called the nucleus. Most of the volume of the atom is empty space through which the tiny, negatively charged electrons are dispersed. There are as many negatively charged electrons outside the nucleus as there are positively charged particles (protons) inside...

Explain the six tenets of Dalton’s atomic theory, and clarify their relation to modern chemistry, understanding as we do now the results of experiments in nuclear chemistry which have resulted in the development of the notions of atomic mass (isotopes) and the failure of the Law of Conservation of Matter. Explain how the theory accounts for the three laws of matter – conservation of matter and energy, definite proportions, and multiple proportions. a) Write the equation for the reaction which...
