Bohr Model REVIEW

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, introduced by Niels Bohr in 1913.

What does the principal quantum number (n) represent in the Bohr Model?

Back

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

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 a photon of light, resulting in specific wavelengths that form the hydrogen emission spectrum.

Front

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

Back

The energy of an electron in the nth energy level is given by the formula E_n = -13.6 eV/n^2.

What is the significance of the Rydberg constant in the Bohr Model?

Back

The Rydberg constant is used to predict the wavelengths of spectral lines in hydrogen and is a key component in the formula for the hydrogen emission spectrum.

Front

What is the concept of quantization in the Bohr Model?

Back

Quantization in the Bohr Model refers to the idea that electrons can only occupy specific energy levels and cannot exist in between these levels.

Front

How does the Bohr Model differ from the Rutherford Model?

Back

The Bohr Model incorporates quantized energy levels for electrons, while the Rutherford Model describes electrons as orbiting the nucleus in a continuous manner without defined energy levels.

Front

What is the relationship between energy levels and electron transitions in the Bohr Model?

Back

When an electron transitions from a higher energy level to a lower one, it releases energy in the form of a photon; conversely, it absorbs energy to move to a higher level.

Front

What limitations does the Bohr Model have?

Back

The Bohr Model does not accurately describe multi-electron atoms or account for electron-electron interactions and does not explain the fine structure of spectral lines.

Front

What is the formula for the wavelengths of spectral lines in hydrogen according to the Bohr Model?

Back

The wavelengths of spectral lines can be calculated using the Rydberg formula: 1/λ = R_H (1/n1^2 - 1/n2^2), where R_H is the Rydberg constant.
