Describe the process of photon absorption by an atom.
An atom absorbs a photon with energy equal to the difference between two energy levels, causing an electron to jump to a higher energy level.
Describe the process of photon emission by an atom.
An electron drops to a lower energy level, emitting a photon with energy equal to the energy difference between the levels.
What is the first step in identifying an element using its spectrum?
Analyze the emission or absorption spectrum to identify the unique set of spectral lines.
What is the process of ionization?
An atom absorbs energy greater than its binding energy, resulting in the removal of an electron and the formation of an ion.
What is the process of electron transition to a higher energy level?
The electron absorbs a photon with the exact amount of energy needed to move to the higher energy level.
Define a photon.
A photon is a discrete packet of light energy.
What is binding energy?
The minimum energy required to remove an electron from an atom.
Define ionization.
The process where an electron is removed from an atom, creating an ion.
What is an emission spectrum?
The unique set of frequencies of light emitted by an element when its electrons transition to lower energy levels.
What is an absorption spectrum?
The unique set of frequencies of light absorbed by an element when its electrons transition to higher energy levels.
Define ground state.
The lowest energy level of an atom.
