Neils Bohr's Atomic Model Quiz

Neils Bohr's Atomic Model Theory

• Building upon Rutherford’s atomic model, Bohr introduced the concept of electrons moving in specific and quantized orbits.
• Electrons can transition between these quantized orbits by absorbing or emitting energy in the form of electromagnetic radiation.

Electron Orbits and Energy Levels

• Electron orbits correspond to energy levels; the position of an electron in these orbits determines its energy.
• Electrons in lower energy levels possess greater stability compared to those situated in higher energy levels.

Energy Absorption and Emission in Atoms

• An atom can absorb energy, causing an electron to ascend to a higher energy level.
• Conversely, an atom can emit energy, which results in an electron transitioning to a lower energy level.
• The energy change during absorption or emission is equivalent to the energy difference between the involved energy levels.

Absorption and Emission of Photons

• Absorption of energy by an atom is associated with the intake of a photon when an electron jumps to a higher energy level.
• Emission of energy occurs when an atom releases a photon as an electron moves to a lower energy level.
• The frequency of the absorbed or emitted photon is directly proportional to the energy difference of the two energy levels.

Stability of the Atom Explained

• An atom's stability is largely dependent on the number of electrons in its outermost energy level.
• A stable atom is characterized by having a completely filled outermost energy level.
• Atoms can achieve stability through the loss, gain, or sharing of electrons.

Limitations of Rutherford's Atomic Model

• Rutherford's model fails to adequately describe the distribution of electrons within an atom.
• It does not account for the mechanisms by which atoms absorb and emit energy.
• Bohr's model addresses these gaps by introducing the idea of electron energy levels and the processes of photon absorption and emission.
