Excited electrons and History of the Atom

What must an electron do to transition from ground state to an excited state?

• Release energy.

• Absorb energy.

• Remain in the same state.

• Increase its mass.

What term describes an atom that has gained energy beyond its normal state?

• Excited

• Energized

• Stimulated

• Activated

What happens to the energy of an electron when it is in an excited state?

• The energy of the electron is lower than in the ground state.

• The energy of the electron is the same as in the ground state.

• The energy of the electron is higher than in the ground state.

• The energy of the electron is unpredictable.

How does energy absorption affect electron configuration in an atom?

• It allows electrons to move to higher energy levels, resulting in an excited state.

• It causes electrons to be ejected from the atom entirely.

• It stabilizes the atom by reducing the energy of the electrons.

• It has no effect on the electron configuration.

What is the significance of the ground state in atomic structure?

• It represents the lowest energy configuration of electrons in an atom.

• It is the state where electrons are at their highest energy level.

• It indicates the presence of unpaired electrons in an atom.

• It describes the arrangement of protons in the nucleus.

What is the role of photons in the excitation and emission of electrons?

• Photons provide the energy needed for excitation and are emitted when electrons return to lower energy levels.

• Photons are responsible for the color of light emitted by electrons.

• Photons absorb energy from electrons during their transition.

• Photons have no role in the excitation and emission of electrons.

What is the process called when an electron moves to a higher energy level?

• Ionization

• Excitation

• Conduction

• Radiation

What does the term 'quantum leap' refer to in atomic physics?

• The gradual transition of an electron between energy levels.

• The sudden transition of an electron between energy levels without occupying the space in between.

• The process of an electron losing energy and moving to a lower energy level.

• The movement of an electron in a circular orbit around the nucleus.

What is the relationship between energy levels and electron stability?

• Electrons in higher energy levels are more stable than those in lower energy levels.

• Electrons in lower energy levels are more stable than those in higher energy levels.

• Energy levels do not affect electron stability.

• Electrons are equally stable at all energy levels.

What is the significance of the Bohr model in understanding electron behavior?

• It introduced the concept of quantized energy levels for electrons in an atom.

• It proposed that electrons move in fixed orbits around the nucleus without energy loss.

• It suggested that electrons can exist in any energy state without restrictions.

• It explained the wave-particle duality of electrons.
