टॉमसन और रदरफोर्ड द्वारा प्रस्तावित परमाणु मॉडलों में क्या अंतर है?
Answers
Answer:
Thomson tells that positive charge is spreas in atom and electrons are embedded in it
Rutherford proves that the protons are situated at centre and electrons move around it
Answer:
The key difference between Thomson and Rutherford model of atom is that ...
Thomson model of atom does not contain any details about nucleus whereas Rutherford model of atom explains about the nucleus of an atom. J.J. Thomson was the first to discover the subatomic particle called electron in 1904.
Explanation:
What is Thomson Model of Atom?
The Thomson model of atom is called Plum pudding model because it states that the atom looks like a plum pudding. The only known details about the atom at that time were,
Atoms are composed of electrons
Electrons are negatively charged particles
Atoms are neutrally charged
What is Rutherford Model of Atom?
According to the Rutherford model of atom, the so-called plum pudding model of Thomson was incorrect. Rutherford model of atom is also called nuclear model because it provides details about the nucleus of an atom.
The famous experiment called “Rutherford gold foil experiment” led to the discovery of the nucleus. In this experiment, alpha particles were bombarded through a gold foil; they were expected to go straight through the gold foil. But instead of straight penetration, alpha particles turned into different directions.
According to this model,
The atom is composed of a positively charged center which is called the nucleus. This center contained the mass of the atom.
Electrons are located outside the nucleus in orbitals in a considerable distance.
The number of electrons is equal to the number of positive charges (later called protons) in the nucleus.
The volume of the nucleus is negligible when compared to the volume of the atom. Hence, most of the space in the atom is empty.
