One weakness of Thomson's atomic model, often referred to as the "plum pudding model," is that it could not explain the results of the Rutherford gold foil experiment. This experiment demonstrated that atoms have a small, dense nucleus at their center, contradicting Thomson's idea of a diffuse distribution of positive charge throughout the atom. Additionally, the model failed to account for the discrete lines observed in atomic spectra, which indicated that electrons occupy specific energy levels rather than being spread uniformly.
What else can I help you with?
What was the name of Dalton model?
Dalton's atomic model is one of the fundamentals of physics and chemistry. John Dalton named this model after himself.
Which atomic model was the first one to include electrons?
The first atomic model to include electrons was J.J. Thomson's "plum pudding model," proposed in 1904. In this model, the atom was envisioned as a sphere of positive charge with negatively charged electrons embedded within it, similar to plums in a pudding. This represented a significant shift from earlier models, which did not account for the presence of electrons. Thomson's model laid the groundwork for further developments in atomic theory, despite being eventually superseded by more accurate models.
What were drawback of atomic model discovered by JJ Thomson?
One drawback of JJ Thomson's atomic model was that it could not explain the distribution of positive charge within the atom. Additionally, it could not account for the stability of atoms with multiple electrons. Ultimately, Thomson's model was replaced by the more accurate and comprehensive model proposed by Ernest Rutherford.
What are two differences between the model of the atom described by Thomson and that described by Rutherford?
Thomsons model described protons to be a large jelly which was positively charged and had negatively charged electrons embedded in it whereas rutherfords model showed protons being in a small nucleus and electrons orbiting around it
What is an error in Rutherfords 1911 model?
One major error in Rutherford's 1911 atomic model is the assumption that electrons orbit the nucleus in fixed paths, similar to planets around the sun. This model could not explain the stability of atoms or the discrete spectral lines observed in atomic emissions. Additionally, according to classical physics, accelerating electrons should radiate energy and spiral into the nucleus, leading to atomic collapse, which does not occur. These limitations were later addressed by Niels Bohr's model, which introduced quantized energy levels for electrons.
Which of the following statements best describes a weakness of the Bohr model of the atom?
The Bohr model fails to fully explain the behavior of atoms with more than one electron, as it simplifies the complex interactions in multi-electron systems. It also does not account for the concept of electron spin or the shape of atomic orbitals.
What was the name of Dalton model?
Dalton's atomic model is one of the fundamentals of physics and chemistry. John Dalton named this model after himself.
Can you draw a bohr model of silicon?
No, the atomic model by Niels Bohr is only applicable to atoms or ions with only one electron.
Where can one find reviews of Thomsons Holidays?
Thomsons eagerly display their positive holiday reviews on their website for all to see. Several websites also focus of reviewing holiday providers so be sure to check reviews on those sites too.

Who Ernest Rutherford?
Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.
Who viewed peace as a weakness and how did they respond to weakness ww2?
No one thought peace was a weakness. It is what a all parties wanted.
What are the strengths and weaknesses of Dalton's atomic model?
strengths: -electrons move fast through the atom. -electrons are trapped within the atom by a positively charged nucleus -electrons are negatively charged. weaknesses: -failed to discover the nucleus contains positively charged particles called protons -failed to discover the nucleus also contains neutrons (a sub atomic neutral particle)
How do you find someones Achilles heel?
Usually by looking for a weakness. No one is perfect, so no one does not have a weakness.
What is Empoleon's weakness?
For some reason one weakness it has is fighting type attacks
