5.3-Atomic Emission Spectra and Quantum Mechanical Model - 3

Who explained that the atomic emission spectrum of hydrogen consists of specific frequencies of light and predicted their values?

• Einstein

• Bohr

• Rutherford

• Dalton

What is the term for an electron in its lowest energy level (1st orbit - K)?

• Excited state

• Emission state

• Ground state

• Neutral state

What is an electron called when it is in the 2nd, 3rd, 4th, 5th, 6th, or 7th orbit of an atom?

• Ground state

• Energy level

• Excited state

• Orbital

What happens when an electron absorbs energy?

• It emits energy and falls to a lower orbit.

• It becomes neutral.

• It splits into smaller particles.

• It gets excited and jumps to a higher orbit.

What happens when an electron releases energy?

• It gains energy and jumps to a higher orbit.

• It gets grounded and jumps to a lower orbit.

• It remains stationary in the same orbit.

• It becomes unstable and leaves the atom.

The frequency of light emitted by an electron is ________ proportional to the energy change of the electron?

• Directly

• Inversely

• mechanically

• electrically

Which series corresponds to the lines in the ultraviolet spectrum when an electron jumps to the n=1 (K-orbit) energy level?

• Balmer series

• Paschen series

• Lyman series

• Rydberg series

The visible spectrum lines formed when an electron jumps to the n=2 (L-orbit) energy level belong to which series?

• Balmer series

• Paschen series

• Lyman series

• Hydrogen series

Which series corresponds to the infrared spectrum lines when an electron jumps to the n=3 (M-orbit) energy level?

• Lyman series

• Paschen series

• Balmer series

• Rydberg series
