What is the difference between the Rutherford model and bohr's model?

Answer 1

According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.

Answer 2

Rutherford showed that the atom consisted of a very dense and very small core (the nucleus), and that the rest was mostly empty space (the electron cloud). By using a backscattering experiment, he watched how alpha particles passed through a very thin gold foil. He found that most of the alpha passed right through the foil with no change in their original direction. However some did change direction, and the ones that did, changed directly significantly. In other words, most of the particles passed through the atoms like nothing was there, but a few hit something as if they hit a brick wall!

Bohr's model of the atom didn't address the question of structure in this way. The Bohr model was used to explain the energy levels of atoms and how atoms absorb and emit light. See the Related Questions to the left for a more complete description of the Bohr model of the atom.

The Bohr model said electrons travel in fixed, circular orbits about the nucleus. We know now that we cannot predict the exact location of an electron in any point in time, and that these electrons exist in "orbitals", and don't travel in circular paths around the nucleus. It is explained by the Heisenberg Uncertainty Principle. The new atomic theory says that electrons are both waves and particles. It is said that just "looking" at an electron (figuratively) would change its position in the atom.

Answer 3

Ernest Rutherford's model of the atom was based upon the gold foil experiment. He basically believed that atoms were built like planetary systems which had all the protons in the nucleus and the electrons orbited around the nucleus like planets around the sun.

The wave-mechanical model views atoms as having the dense nucleus surrounded by electron clouds which are localized probability regions described by quantum mechanics.

Answer 4

Based on his gold foil scattering experiment, Rutherford proposed the atomic planetary model where is suggested that there is a positively charged nucleus with the electrons revolving around it. He didnt propose the path in which electrons are moving.

According to Bohr, the electrons travel around the nucleus in fixed path called orbits. The electrons could jump between these orbits either by losing energy or gaining energy.

Answer 5

Rutherfords model had a positive nucleus at the centre of the atom surrounded by electrons. Thomsons had electrons moving through a "sea of positive charge", sometimes called the plum pudding model.

Answer 6

Both Thomson and Rutherford made incredible discoveries when it comes to understanding the atom.

In the late 1800s, Thomson discovered that atoms are are created from positive and negative charges. Thomson guessed that the negative charges were sprinkled throughout the positive charges. (This is often compared to Chocolate Chips sprinkled through a slab of cookie dough.)

In the 1900s, Rutherford discovered that all the positive charges were in the center of the atom and that the atom is mostly empty space. His discovery formed the idea of a positively-charged nucleus and that the electrons (the negatively-charges) travel around this nucleus and are not "sprinkled" like Thomson had suggested over 100 years prior.
