Rutherford explained that all the positive charge was concentrated at the centre and the electrons revolved around it.
But this theory was discarded as a charged particle undergoing circular motion would
accelerate and an accelerating particle looses energy. Hence, the electron would fall into the nucleus and the atom will collapse.
But this doesn't happen. So, Rutherford's model of atom was discarded.
Inability of stability of nucleas.
Inability of the explain line spectra of element.
Inability of describe the distribution of elactron and electron energies.
Rutherford's atomic theory failed to explain the stability of atoms without collapsing due to accelerating electrons, the distribution of electrons within the atom, and the emission spectrum of atoms. It also couldn't account for the existence of isotopes or the details of chemical bonding.
Rutherford explained that all the positive charge was concentrated at the centre and the electrons revolved around it.
But this theory was discarded as a charged particle undergoing circular motion would
accelerate and an accelerating particle looses energy. Hence, the electron would fall into the nucleus and the atom will collapse.

But this doesn't happen. So, Rutherford's model of atom was discarded.
Rutherford's model of atom stated that all the positive charge was concentrated in the center together and electrons revolved around it but the classical theory of physics states that "If a charged particle undergoes circular motion, then it is subjected to accelerate and
an accelerating particle would loose energy".
Thus, the electrons revolving around the nucleus would go in a spiral path and ultimately
fall into the nucleus as there path will continue to shrink and the atom will collapse. But this does not happen.
So, Rutherford's model of atom was discarded.
Shortly: a positive nucleus float in a sea of negative electrical charges.

Did bohr proove that atoms exist?
No, Bohr did not prove that atoms exist. However, he made significant contributions to the atomic theory by proposing a model that explained the stability of atoms and the emission of spectral lines by electrons. His model laid the foundation for our current understanding of atomic structure.
What contribution to atomic theory was made by Geiger and Marsden in their gold foil experiment?
Geiger and Marsden's gold foil experiment provided evidence for the existence of a dense nucleus at the center of an atom, based on the unexpected deflections of alpha particles being scattered at large angles. This supported the model proposed by Ernest Rutherford, which revolutionized atomic theory by introducing the concept of a small, positively charged nucleus surrounded by negatively charged electrons.
Whose ideas led to the atomic theory of matter?
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
What is the first theory to relate chemical changes to events at the atomic level?
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
Who proposed the first modern atomic theory?
The first modern atomic theory was proposed by John Dalton in the early 19th century. Dalton's theory stated that all matter is made up of tiny, indivisible particles called atoms, and that atoms of different elements have different masses and properties.
How was Thomsons atomic theory different from Rutherfords atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
What were Lord Ernest Rutherfords Accomplishments?
he found faults in the atomic theory of jj Thompson
What is the rutherfords atomic model?
Because Joel is the man
What idea did Rutherford add to the atomic theory?
the idea behind rutherfords atomic theory is that the atom has a central positive nucleus and negatively charged electrons, which move in orbits, surround it. most of the atom is made up of empty space. he assumed this theory through a gold-foil experiment about which you can find information on the internet.
Was Rutherfords theory tested and published?
yes it was tested by the gold foil experiment
One of the shortcomings of the theory of historical particularism is?
'''an overemphasis on sociocultural differences'''
What was Rutherfords atomic theory?
it looks like cheese on my balls with ketchup and mustard with applesuace
What was ernest rutherfords greatest science achievement?
Opinions vary. The discovery of the atomic nucleus ("most of the atom is empty space")
What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
How Do You Use The Word atomic theory in A Sentence?
when i was atomic theory i was a smart
Atomic theory invented by?
Atomic theory was founded by John Dalton. He proved this theory in 1803.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
