The major shortcoming of Rutherford's model of the atom did not explain how the atom's negatively charged electrons occupy the space surrounding its positively charged nucleus. Rutherford's model included a small central nucleus of positive charge surrounded by a cloud of electrons.
Rutherford and other scientists had guessed that electrons move around the nucleus as planets move around the sun. * accelerating charges produce some kind of light or electromagnetic radiation.
an electron traveling around a nucleus in a circular orbit is constantly accelerating because it is changing it's direction. And according to classical theory , these electrons should emit photons of electromagnetic radiation, losing energy in the process. because they lose energy, they should ultimately collapse into the nucleus. but this does not happen in real life. the materials we see around us are obviously stable ,and because of that reason , they must be composed of stable atoms.
basically, without realizing the existence of energy levels among electrons, he could not explain the chemical properties of an atom. Also, without the ability to jump into an orbit closer to the nucleus when an electron looses energy, the atom would implode ... ouch -- black hole ... but that's another subject
It did not explain how the atom's negatively charged electrons are distributed in the space surrounding it's positively charged nucleus.

Inability of stability of nucleas.
Inability of the explain line spectra of element.
Inability of describe the distribution of elactron and electron energies.
Couldn't explain the chemical properties of elements
Rutherford did not foresee the movement of electrons around the nucleus.
His experiment with the gold foil and the beam of positively charged particles proved that the nucleus of the atom is not solid. The beam past through the foil and bounced back. Rutherford's experiment contradicted Thomson's theory that an atom is solid.
Rutherford's model of the atom was one that resembled the solar system. The nucleus took the place of the sun, at the centre. The electrons followed well-defined orbits around the nucleus so that it should be possible to determine the location and motion of the electrons. In fact, electrons orbit the nucleus in a cloud. It is not possible to know their position and momentum at the same time.
The Rutherford model, or the nuclear model
its larger
a new model of the atom that describe electrons as being in a cloud
incorrect
Rutherfords Model is Rutherfords Model... thats it, its just a model.. go look it up on google images im sure you will figure it out by then.
Niels Bohr introduced the notion of electronic orbits.
The Rutherford model involve a positive nucleus separated from electrons.
The atomic model of Rutherford was a step in the historical development of the today concept of an atom.
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Negative electrons orbiting a positive nucleus much like the planets orbit the sun.
The Bohr Model is the modern name used by scientist for a model of an atom, which is often referred to as the Rutherford-Bohr model due to the fact that Neils Bohr just improved Ernest Rutherfords model.
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
im awesome!
That the atom Mostly consisted of empty space.- apex
