The Japanese scientist H. Nagaoka modelled the atom as a large positive sphere surrounded by a ring of negative electrons. The atom is compared with the planet Saturn, where the planet represents the positively charged part of the atom, and the rings represent the negatively charged electrons. This model was made in 1904. Information from Science9 by Nelson.
the planets in orbit around the central sun is a little bit like the electrons in an atom orbiting around the nucleus of the atom.
the Bohr Model
The Bohr Model
Bohr's model
Niels Bohr's "solar system" model of the atom was an attempt to explain the spectrum of the hydrogen atom. The model had a negative electron orbiting a positive proton, but the electron was only allowed to occupy particular energy levels. The model worked well, but lacked any theoretical basis. The wave mechanical model gave a reason for the restricted energy levels in terms of the wave properties of electrons. This developed into "quantum mechanics" which is probably the most important theory in modern physics.
The Greek model of the solar system was developed by one Claudius Ptolemy.
A many-particle system where the behavior of each particle at every instant depends on the positions of all the other particles cannot be solved directly. This is not a problem restricted to quantum mechanics. A classical system where the same problem arises is a solar system with several planets. In classical mechanics as well as in quantum mechanics, such a system has to be treated by approximate methods
nitrogen and oxygen atom absorb solar radiation.
Electrons orbit around the nucleus in all sorts of crazy shapes, where as planets orbit around the sun in just a circle. yes that's right but still there are some similarities and differences like the atom are disscused in subatomic energy and have subatomic particles
The Bohr atomic model is similar to solar system.
It is similar to a solar system. The sun is the nucleus with protons and neutrons and the electrons are the planets.
The Bohr model describes an atom as having a central nucleus where most of the mass is concentrated, around which electrons orbited at discrete distances, somewhat like the solar system with the sun where the atom's nucleus would be (and again, most of the mass) and the planets orbiting it. In an atom, electrostatic forces attract the electrons to the nucleus; in the solar system, gravity is the binding force.
It is nicknamed the "planetary Model" because it resembles the solar system.
Neils Bohr proposed Bohr model of the atom,which states that atom is a small,positively charged nucleus and is surrounded by electrons which travel in circular motions because of electrostatic forceand is similar to the solar system..
The atom and the solar system are not equal. The solar system contains the sun and the other planets.
The Bohr's atomic model is similar to planetary system.
The mechanical model shows the nucleus surrounded by electrons similar to the solar system. The quantum model shows a nucleus surrounded by a cloud of electrons shaped like a doughnut.
No, the solar system is not a atom. Atoms make up things around you and are very, very small.
Niels Bohr's 1913 model was the first to depict the atom as small positively charged nucleus in the center with negative charged electrons circling around it, similar in shape to the solar system. Though quantum theory has made his model obsolete. it is a simple and good enough approximation it's still be taught today when introducing students to the atom.
The atomic model of Niels Bohr is similar to planetary system of Sun (Sun being the equivalent of the atomic nucleus).
The best model to describe atomic structure is the Rutherford model
