Topic 3 - The Atomic Structure
18. Ground state and Excited state: Recalling concept facts and definitions
1. As an electron of an atom moves from the ground state to the excited state, its energy
1) Decreases 2) Increases 3) Remains the same
2. As an electron of an atom moves from the excited to the ground state, the total energy of the atom
1) Decreases 2) Increases 3) Remains the same
3. When compared with the energy of a carbon atom in the excited state, the energy of the carbon
atom in the ground state is
1) Greater 2) Lower 3) Same
4. What happens as an electron in an atom moves from a high electron shell to a lower electron shell?
1) The energy of the electron increases

2) The energy of the electron decreases
3) The total number of electrons increases
4) The total number of electrons decreases
5. Compared to a sodium atom in the ground state, the sodium atom in the excited state must have
1) A greater number of electrons 3) An electron with greater energy
2) A smaller number of electrons 4) An electron with smaller energy
6. As an electron in an atom moves from the ground state to the excited state, the electron
1) Releases energy as it moves to a lower energy level
2) Releases energy as it moves to a higher energy level
3) Absorbs energy as it moves to a lower energy level
4) Absorbs energy as it moves to a higher energy level
7. When an electron in an atom moves from the excited state to the ground state, the result is the
1) Absorption of energy by the electron as it moves to a lower energy state
2) Absorption of energy by the electron as it moves to a higher energy state
3) Emission of energy by the electron as it moves to lower energy state
4) Emission of energy by the electron as it moves to a higher energy state
8. As an electron moves from a higher energy level to a lower energy level, the electron will
1) Lose energy 2) Lose a proton 3) Gain energy 4) Gain a proton
9. When an electron in excited atom returns to a lower energy state, the energy emitted can result in
the production of 3) Isotopes
1) Alpha particle
2) Protons 4) Spectral lines
10. The characteristic bright-line spectrum of an element occurs when electrons
1) Move from lower to higher energy levels 3) Are lost by a neutral atom
2) Moves from higher to lower energy levels 4) Are gained by a neutral atom
11. During a flame test, ions of a specific metal are heated in the flame of a gas burner. A characteristic
color of light is emitted by those ions in the flame when the electrons
1) Gain energy as they return to lower energy levels
2) Gain energy as they return to higher energy levels
3) Emit energy as they return to lower energy levels
4) Emit energy as they return to higher energy levels
12. Electron X can change to a higher or a lower electron shell. Which statement is true of electron X?
1) Electron X absorbs energy and produces spectral lines when moving to lower shell
2) Electron X absorbs energy and produces spectral lines when moving to higher shell
3) Electron X emits energy and produces spectral lines when moving to lower shell
4) Electron X emits energy and produces spectral lines when moving to higher shell
