    Which statement describes how an atom in the ground state becomes excited?

    • The atom absorbs energy, and one or more electrons move to a higher electron shell.

    • The atom absorbs energy, and one or more electrons move to a lower electron shell.

    • The atom releases energy, and one or more electrons move to a lower electron shell.

    • The atom releases energy, and one or more electrons move to a higher electron shell.

    Correct Answer
    A. The atom absorbs energy, and one or more electrons move to a higher electron shell.
    Explanation
    Electrons become excited by absorbing energy in forms like heat or light.

    The light emitted from a fireworks display is produced when electrons in an excited state

    • Absorb energy as they move to lower energy states

    • Release energy as they move to higher energy states

    • Release energy as they move to lower energy states

    • Absorb energy as they move to higher energy states

    Correct Answer
    A. Release energy as they move to lower energy states
    Explanation
    Absorbing energy in forms like heat or light causes electrons to become excited. The opposite occurs during energy emission.

    Based on the bright-line spectra below, identify the two gases present in the mixture. In writing your answer, capitalize the two letters and separate them with a space and a comma. (Ex: X, Y)  - ProProfs

    Based on the bright-line spectra below, identify the two gases present in the mixture. In writing your answer, capitalize the two letters and separate them with a space and a comma. (Ex: X, Y) 

    Correct Answer
    A, D
    A and D
    Explanation
    See which elements have lines in the exact same spots as the mixture does.

  • 5. 

    Which of the following describes how colors in a bright-line spectrum or in a fireworks display are produced?

    • Ions in salts absorb a specific amount of energy and become excited

    • Ions in salts absorb a specific amount of energy, moving to a lower energy state as a result

    • Ions in salts release a specific amount of energy as the electrons move from a higher energy state (excited state) to a lower energy state

    • Ions in salts release a specific amount of energy as the electrons move from a lower energy state to a higher energy state (excited state)

    Correct Answer
    A. Ions in salts release a specific amount of energy as the electrons move from a higher energy state (excited state) to a lower energy state
    Explanation
    Remember: Colors in a bright-line spectrum or in a fireworks display are produced when electrons emit a specific amount of energy in the form of light with specific wavelengths as the electrons move from higher, excited energy states to lower energy states.

  • 6. 

    The isotopes C-12 and C-13 have the same  

    • Mass number for their atoms

    • Bright-line spectrum

    • Number of neutrons in their atoms

    • Decay mode

    Correct Answer
    A. Bright-line spectrum
    Explanation
    Each element has a specific bright-line spectrum. Isotopes DO NOT change the identity of an element. They are different forms of the same element, so the bright-line spectrum is still the same, even if only the number of neutrons and the mass number change.

    Rate this question:

  • 7. 

    A specific amount of energy is emitted when electrons in an aluminum atom return to the ground state. This emitted energy can be used to do what?

    • To determine the mass of the sample

    • To determine the identity of the element

    • To determine the number of moles of the element

    • To determine the number of electrons, ONLY, and NOTHING ELSE

    Correct Answer
    A. To determine the identity of the element
    Explanation
    Remember: Colors in a bright-line spectrum or in a fireworks display are produced when electrons emit a specific amount of energy in the form of light with specific wavelengths as the electrons move from higher, excited energy states to lower energy states. These wavelengths and specific emitted energies can be used to determine the identity of the element itself.
