Answer:
What are the main features of the rutherford model?
Atom is spherical and consists of part : Nucleus and extra-nucleus part.
The entire mass and entires positive charge is concentrated in a very small region at the centre known as nucleus .
The space surrounding the nucleus known as extra-nuclear part is negatively charged so an atom as a whole is neutral .

Answer:
Rutherford proposed that an atom is composed of empty space mostly with electrons orbiting in a set, predictable paths around fixed, positively charged nucleusThe 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..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.
