What are the faults and shortcomings of Bohr's atomic theory?
Deficiencies in the Bohr Atomic Model It cannot explain the spectra of multi-electron atoms. Wave-particle duality (De Broglie Hypothesis) is not considered in the Bohr Atomic Model. According to the Heisenberg uncertainty principle, the position and velocity of the electron in an atom cannot be determined simultaneously with complete precision.
What did Bohr not explain?
Bohr's atomic model is considerably superior to Rutherforad's atomic model. Although there are aspects of this Bohr theory, there are also deficiencies. In spectrum analysis, Bohr could not explain that some lines are brighter than other lines.
Does the electron radiate in its ground state?
By energizing an atom in the ground state, it can release its electron. The process of removing one of the higher levels is called excitation of the atom. Radiation by atoms is related to raising the energy levels of electrons. Radioactive substances radiate spontaneously.
How did the modern atomic Theory explain the position of electrons around the nucleus?
According to the Modern Atomic Theory;
A certain energy in the atom has level. Principal quantum numbers indicate how far the electrons are from the nucleus. Electrons do not emit light to the environment during their movement at an energy level.When does an atom emit light according to Bohr?
Question: When does an atom emit light according to Bohr? Answer: The electron, which makes circular motion to the energy level closest to the nucleus, is stable and does not emit light. If enough energy is given to the electron, the electron jumps from its current energy level to a higher energy level. The atom radiates in this way.
Which atomic model of absorption and emission?
As the hydrogen atom has a simple structure, we can explain the absorption and emission spectra starting from this atom.
What does it mean for an atom to radiate?
Excitation of atoms means; It is the displacement of electrons by effects such as heat, light, energy and magnetic field. The transfer of electrons to a higher energy level by external influence is called radiation. Radiation by atoms is related to raising the energy levels of electrons.
