What are the discrete energy orbits in the Bohr model called?
Quantum energy levels.
What is the lowest energy level in the Bohr model called?
Ground state (E0).
How does the energy of an electron relate to its distance from the nucleus?
The further from the nucleus, the more energy the electron must have.
What type of spectrum is produced by white light passed through a prism?
A continuous spectrum.
What type of spectrum is produced by light from stars or electrical discharge lamps?
A line spectrum.
What causes the bright lines in a line spectrum?
Electrons transitioning from excited states to lower energy states.
What happens when an electron loses energy during a transition?
It emits a photon.
What formula relates the energy of a photon to its frequency?
E = hf.
What does E represent in the formula E = hf?
The energy of the photon measured in joules (J).
What does h represent in the formula E = hf?
Planck’s constant, h = 6.63 × 10⁻³⁴ Js.
What does f represent in the formula E = hf?
The frequency of the emitted photon measured in hertz (Hz).
What is the significance of the energy difference between two levels?
It determines the frequency of the emitted photon.
How many different energy transitions are mentioned in the notes?
Six different energy transitions.
What does each element produce in terms of energy levels?
A unique set of energy levels and corresponding spectral lines.
What is the relationship between the number of spectral lines and energy jumps?
More lines indicate a larger number of possible energy jumps.
What is the formula for the energy difference between two energy levels?
E2 - E1 = hf.
What does E2 represent in the energy difference formula?
The upper energy level measured in joules (J).
What does E1 represent in the energy difference formula?
The lower energy level measured in joules (J).
