Answer :
The three reasons that scientists found Rutherfor's nuclear atomic model to be fundamentally incomplete are as follows:
Number 1) according to Rutherford, the electrons revolve in completely circular orbits. However, if this was true the charged electron would simply fall into the nucleus after losing energy.
Number 2) According to Rutherford's model, the nucleus itself only consisted of protons. However, as we now know due to research in quantum mechanics, if this was true this would make the atom unstable due to the cycle of attraction and repulsion.
Number 3) The neutrons which have also been discovered since to be an important part of the atom, are not mentioned at all in Rutherford's model.

The correct answer is:
1.how electrons are organized in a cloud
2. why electrons are not attracted into the positively charged nucleus
3. variations in chem behavior between elements
Explanation:
Rutherford reversed Thomson's model in 1911 with his popular gold foil research in which he confirmed that the atom has a tiny and massive nucleus. Rutherford created an experiment to practice the alpha particles released by a radioactive element as probes to the underground world of atomic structure.
