question #6
classify each of the following statements about the bohr model of the atom as true or false.
bohr proposed that the line spectra of hydrogen was produced by electrons absorbing and emitting specific quantities of energy.
according to the bohr model of the atom, when an electron transitions from an orbit of lower energy to an orbit of higher energy, it emits energy.
the bohr model of the atom was able to account for the line spectra of several different elements.
the bohr model of the atom is the currently held theory of atomic structure.

Explanation:

• First statement: In the Bohr model, electrons can absorb energy to move to higher - energy orbits (excited state) and emit energy (in the form of light with specific wavelengths corresponding to specific energy differences) when they return to lower - energy orbits. So, the statement "Bohr proposed that the line spectra of hydrogen was produced by electrons absorbing and emitting specific quantities of energy" is True.
• Second statement: When an electron transitions from an orbit of lower energy to an orbit of higher energy, it absorbs energy. When it goes from a higher - energy orbit to a lower - energy orbit, it emits energy. So, the statement "According to the Bohr model of the atom, when an electron transitions from an orbit of lower energy to an orbit of higher energy, it emits energy" is False.
• Third statement: The Bohr model was mainly successful in explaining the line spectra of hydrogen - like atoms (atoms with one electron). It could not account for the line spectra of multi - electron atoms. So, the statement "The Bohr model of the atom was able to account for the line spectra of several different elements" is False.
• Fourth statement: The Bohr model has limitations (e.g., it does not fully explain the behavior of electrons in multi - electron atoms, and it does not incorporate the wave - like nature of electrons as described by quantum mechanics). The currently held theory of atomic structure is based on quantum mechanics (e.g., the Schrödinger equation and the concept of electron orbitals). So, the statement "The Bohr model of the atom is the currently held theory of atomic structure" is False.

Answer:

1. True
2. False
3. False
4. False
