Bohr Model Flashcard

Front

What is the Bohr Model?

Back

The Bohr Model is a theory of atomic structure that depicts electrons orbiting the nucleus in defined paths or energy levels.

Front

Who proposed the Bohr Model?

Back

The Bohr Model was proposed by Danish physicist Niels Bohr in 1913.

What are energy levels in the Bohr Model?

Back

Energy levels are the fixed distances from the nucleus where electrons can orbit, each corresponding to a specific energy state.

Front

How does the Bohr Model explain the emission spectrum of hydrogen?

Back

The Bohr Model explains that when an electron transitions between energy levels, it emits or absorbs energy in the form of light, producing spectral lines.

Front

What is the formula for calculating the energy of an electron in a specific energy level in the Bohr Model?

Back

E_n = -13.6 eV/n^2, where E_n is the energy of the electron at level n.

What is the significance of the principal quantum number (n) in the Bohr Model?

Back

The principal quantum number (n) indicates the energy level of an electron, with n=1 being the closest to the nucleus.

Front

What limitations does the Bohr Model have?

Back

The Bohr Model does not accurately describe atoms with more than one electron and fails to account for electron-electron interactions.

Front

How does the Bohr Model relate to the concept of quantization?

Back

The Bohr Model introduces the idea that electrons can only occupy certain quantized energy levels, rather than any value.

Front

What is the relationship between wavelength and energy in the context of the Bohr Model?

Back

The energy of a photon emitted or absorbed during electron transitions is inversely proportional to its wavelength (E = hc/λ).

Front

What is the Bohr radius?

Back

The Bohr radius is the average distance between the nucleus and the electron in the ground state of hydrogen, approximately 0.529 Å.
