Dyslexia is not due to either lack of intelligence or. desire to learn; with appropriate teaching methods, students with dyslexia can learn successfully. Dyslexia occurs in people of all backgrounds and intellectual levels. People with dyslexia can be very bright.
The Bohr's Theory. The discoveries of the electron and radioactivity at the end of the 19th century led to different models for the structure of the atom. In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities.Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.n 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities.
In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.ecause of the quantization, the electron orbits have fixed sizes and energies. The orbits are labeled by an integer, the quantum number n. With his model, Bohr explained how electrons could jump from one orbit to another only by emitting or absorbing energy in fixed quanta.
