Was Rutherford correct about the structure of the atom? Why did Bohr study Rutherford’s model again?

Answer:
Rutherford’s Model of an Atom
We know a structure of an atom consists of electrons, protons, and neutrons. This was accurately presented after several scientists came up with different models. The classic model of an atom was given by Ernest Rutherford called the Rutherford atomic model or Rutherford model of the atom. However, it is not considered the accurate representation of an atom anymore. Let us know more about this model.
Rutherford Atomic Model
Rutherford proposed that an atom is composed of empty space mostly with electrons orbiting in a set, predictable paths around fixed, positively charged nucleus.
The concept of atom dates back to 400 BCE when Greek philosopher Democritus first conceived the idea. However, it was not until 1803 John Dalton proposed again the idea of the atom. But at that point of time, atoms were considered indivisible. This idea of an atom as indivisible particles continued until the year 1897 when British Physicist J.J. Thomson discovered negatively charged particles which were later named electrons.
To understand this concept in more detail you should read the Structure of Atom
He proposed a model on the basis of that where he explained electrons were embedded uniformly in a positively charged matrix. The model was named plum pudding model. However, J.J. Thomson’s plum pudding model had some limitations. It failed to explain certain experimental results related to the atomic structure of elements.

Answer:
Explanation:
Rutherford's model of an atom was correct. He was able to explain the neutral nature of the atom better than JJ Thomson. His contribution was very important. However, he could not explain the stability of atom. According to one of the laws Physics, when a body is in accelerated motion, it loses or radiates energy. So the electrons will continuously lose energy and will fall into the nucleus. This was the drawback of Rutherford's model of atom.
Neil Bohr modified the model and said that electrons move around the nucleus in a particular path called orbit only, it does not lose energy.
