He discovered the electron cloud model theory and made the Sschrodinger equation, which is the foundation for the quatum mechanics in its wave formation. He aslo had a partner named Wermer Heisenburg.

Niels Bohr created the Bohrs model of the atom. This Danish physicist won a Nobel Prize in Physics for his developments in atomic structure and quantum physics.

He formulated his atomic model (electrons orbiting the nucleus) in 1913.

In Bohr model Helium, the two electrons are moving on the same orbital. But this model could not explain the experimental value of the Helium ground state energy correctly. When the orbital planes of the two electrons are perpendicular to each other, the two orbitals are proved to be just one de Broglie's wave length by the computatinal methods. Please see the link below.

Introduced by Niels Bohr in 1913, the model's key success lay in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen.
The Bohr model is a primitive model of the hydrogen atom. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics, and thus may be considered to be an obsolete scientific theory. However, because of its simplicity, and its correct results for selected systems , the Bohr model is still commonly taught to introduce students to quantum mechanics, before moving on to the more accurate but more complex valence shell atom.

my babe!

Easy. Get the valence of fluorine ( no. of electrons on outermost orbital) and the protons and neutrons. Obtain a wire coat hanger and form into circle about 8 inch diameter. Form another wire hanger but smaller diameter, say 6 inches. Create or obtain plastic or styrofoam balls. Attach it to the outer ring ( 8 electrons). Add 2 balls to the inner ring. Create a mound using aluminum foil then stick a smaller balls representing neutrons and protons. Run a string to all rings and mound, Color it and label it. Done.

In 1938 Bohr worked with Albert Einstein and carried out atomic research; was elected president of the Danish Academy of Science and was an advisor to the Manhattan Project, which produced the first atomic bomb.

There you go. :)

Doesn't show Protons or Neutrons. I am pretty sure it has 98 protons and 153 neutrons.

Valence Electrons = 2

Valence # = 2

Hope this helped.

When a gas is excited in an electrical discharge, light is emitted (this is essentially how neon lamps work). Niels Bohr looked at this emitted light using a spectrograph, which separates different wavelengths of light (just a like a simple triangular prism). Atoms, such as hydrogen or neon, emit very specific patterns of light. When you separate the wavelengths, you see a pattern of very sharp lines of light at only certain wavelengths and not others. In other words, the atoms emit only certain wavelengths of light, resulting in a series of lines when you look at the light through a spectrograph. Bohr looked at these lines and managed to figure out the pattern that determined which wavelengths were observed. He said that the light emitted was due to transitions between energy levels in the atoms, and the wavelength of light corresponded to the energy difference between the two states involved in the transition. In this way, he figured out the equation to predict the spacing between all of the energy levels of any one-electron atom or ion. His model was quite successful, and he was able to predict which lines you would see for things that hadn't even been measured yet (a good test for any theory!). Surprisingly, although he figured out the pattern so well, he didn't actually know what the patterns were really due to. In fact, he had to make assumptions that turned out to be completely false! However, despite these errors (which were corrected when quantum mechanics was developed), the Bohr model of the atom is very useful for many applications. His model does NOT work well for multi-electron atoms/ions, which unfortunately includes the large majority of atoms and ions! You need quantum mechanics for that!

Thomson proposed that negative electrons were located throughout a positively-charged atomic mass like plums in a pudding. Rutherford's experiments revealed that most of the mass of an atom was concentrated in a tiny region in its center, the nucleus, surrounded by nearly-massless electrons in their orbitals.

The electrons have a set amount of energy, arranged into levels of increasing energy the farther they are from the nucleus. So, for example, E=1 is the first energy level where the energy of the electron is what that energy level is too.

Also, as you go out, the energy levels get closer together. So, E3 and E2 are closer together than E1 and E2.

Basically, electrons cannot have an energy lower than the first energy level. It would have to be lower for the electron to get to the nucleus. But it cannot go that low. Bohr discovered that it happened, and I think we're still looking for why it doesn't

The model that simply showed atoms as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus-similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity.

The Bohr model was made around 1913. There isn't an exact date, it's unknown.

He discovered this in 1764

The orbital revolutionof the electron is not expected to be stable.Any particle in a circular orbit would undergo accleration.

During accleration,charged particles would radiate energy.Thus,revolving electrons would lose energy and finally fall into nucleus.If they were so,the atom would be highly unstable and hence matter would not exist in the form that we know.We know that atoms are quite stable.

Politically he was struggling with Roosevelt and especially Churchill to convince them that the secret of nuclear weapons production should be shared with the Soviets via the UN. Churchill allegedly thought that Bohr was a &¤#%& communist - which he certainly was not.

Electrons orbit the nucleus in specific shells. The K shell is the closest to the nucleus, and is followed by the L, M, N, O, and P shells, which move further out as the letter increases.

Niels Bohr won the Nobel Prize for his groundbreaking work in atomic structure and the development of quantum theory. Bohr's work helped to revolutionize physics, as his models of the atom and quantum mechanics explained the behavior of electrons, allowing for a deeper understanding of the physical world. Specifically, Bohr was awarded the Nobel Prize in Physics in 1922 for his:

• Discovery of the structure of the atom
• Development of the Bohr model of the atom
• Proposal of the principle of complementarity
• Explanation of the behavior of electrons in atoms

Bohr's work provided the foundation for much of the research that followed and demonstrated the importance of collaboration in the physical sciences. His Nobel Prize was a recognition of the significance of his contributions to the field of physics.

Niels Bohr created the planetary model of the atom, including the nucleus and electrons. This, however, is not the accurate model of atoms. It is said to be the electron cloud which is most accurate

Bohr studied the spectrums of various atoms and generalized his quantum theory from his discoveries. He concluded that the electrons of an atom determined many of its characteristics.

Niels Bohr was born in 1885, 7 October, second born of Christian Bohr and Ellen Adler Bohr. He had a younger brother Harald and an older sister, Jenny. Nies liked to play football together with his brother. He started school at seven and attended Gammelholm Latin School.
