5 Questions
According to Bohr's model of the atom, what is the behavior of electrons in discrete orbits?
They do not radiate energy while revolving in discrete orbits
How are the orbits of electrons arranged according to Bohr's model?
Concentrically around the nucleus
What is the behavior of electrons in Bohr's model when jumping between energy shells?
They absorb or emit a definite amount of energy
Why did Rutherford's model fail to explain the stability of atoms?
It could not explain why the revolving electron did not lose energy and fall into the nucleus
What did Bohr propose about the orbits in which negatively charged electrons revolve?
They revolve only in those orbits which have a fixed value of energy
Study Notes
Bohr's Model of the Atom
- Electrons occupy specific energy levels (discrete orbits) around the nucleus, jumping from one energy level to another by emitting or absorbing energy.
- Orbits are arranged in a series of concentric circles (shells) around the nucleus, with each shell having a specific energy level.
Electron Behavior in Bohr's Model
- When jumping between energy shells, electrons emit or absorb energy in the form of photons.
- Electron transitions between energy shells are accompanied by the emission or absorption of energy.
Limitations of Rutherford's Model
- Rutherford's model failed to explain the stability of atoms because it did not account for the energy levels of electrons.
Bohr's Proposal on Electron Orbits
- Electrons revolve in specific, stable orbits (energy levels) around the nucleus, rather than collapsing into the nucleus due to electrostatic attraction.
