The plum pudding model of the atom, forwarded by J.J. Thomson, stated that the atom was like a plum pudding. The negatively charged electrons were evenly distributed throughout a positive "web" or "soup" much like plums in plum pudding are distributed here and there in the pudding.
It was Rutherford, based on his observations with the gold foil experiment, who was able to push this theory aside and cause a shift in thinking to the idea that most of the mass of the atom was concentrated in a small volume within a given atom.
The plum-pudding atomic model, proposed by J.J. Thomson in 1904, suggested that atoms were composed of a uniform positive sphere of matter with negatively charged electrons randomly distributed throughout. This model was later replaced by the Rutherford model, which introduced the concept of a tiny, dense nucleus at the center of the atom surrounded by orbiting electrons.
Thomson originally thought that in an atom all of the neutrons and protons are spread evenly throughout the atom (as opposed to the more modern model which suggests that actually the mass is mostly concentrated in one small area; the nucleus).
A description of electrons scattered inside the atom (Apex 2021)
Electrons were added in the Plum Pudding Model. At the time they were known as corpuscles. The model was intended to show how electrons were arranged in the atom relative to protons.

Thomson supposed that an atom is formed from electrons floating in a "pudding" formed from positively charged particles.

What is the relationship between atomic radius and the corresponding model radius?
Atomic radius refers to the size of an atom, while model radius is the size of the atom as represented in a molecular or atomic model. In most models, the model radius is larger than the atomic radius in order to make the structure more visible and distinguishable. The relationship between the two is that the model radius is typically proportional to the atomic radius but scaled up for clarity.
Are there any limitations of Chadwick's atomic model?
Yes, Chadwick's atomic model did not fully explain the properties of the electron cloud or electron behavior within an atom. It also did not delve into the concept of electron energy levels and their relationship to atomic spectra.
What are the 7 atomic models in chronological order?
Atomic model of DemocritusAtomic model of DaltonAtomic model of ThomsonAtomic model of RutherfordAtomic model of BohrAtomic model of SommerfeldSchrödinger model
What is the name of Schrodinger atomic model?
The Schrödinger atomic model is known as the Quantum Mechanical Model or the Wave Mechanical Model. It describes electrons in atoms as standing waves guided by probability equations rather than fixed circular orbits.
What is the atom model called?
The atom model is called the "Bohr model," named after Niels Bohr who proposed it in 1913. This model describes the atom as a small, positively charged nucleus surrounded by negatively charged electrons in specific energy levels or orbits.
Is an atomic model extremely accurate?
The atomic model cannot be extremely accurate.
How is the Bohr model better than the Rutherford model?
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
How does the atomic model you used today differ from Bohr model?
The modern atomic model is based on quantum mechanics.
What Components Make Up The Atomic Model?
The atomic model includes protons, electrons and neutrons.
What additions or correction were made to Dalton atomic model?
An atomic model from Dalton doesn't exist.
The Bohr model of atomic structure?
Niels Bohr propose a planetary model for the atomic nucleus.
How did Thomson's' experiment change Dalton's atomic model?
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
Who form the atomic theory model of the atom?
Niels Bohr is considered the founder of the modern atomic model.
What atomic model did Jabir Ibn Hayyan discover?
An atomic model from Jabir Ibn Hayyan is not known.
What are the other general example of atomic models other than plum pudding atomic model?
Bohr's planetary model Rutherford's model
Chadwick's atomic model?
Chadwick's atomic model, proposed by James Chadwick in 1932, introduced the concept of the neutron in the atomic nucleus. This model helped to explain the stability of the nucleus and resolved some of the issues with the Rutherford atomic model, specifically the absence of sufficient mass in the nucleus to account for its positive charge. The discovery of the neutron as a neutral particle in the nucleus was a significant advancement in our understanding of atomic structure.
Why is the atomic model a scientific model?
Because this model was experimentally demonstrated.
