All Flashcards
In a PES spectrum, what information do the X and Y axes provide?
X-axis (Binding Energy): Energy needed to remove an electron. Y-axis (Intensity): Number of electrons in that subshell.
What does the peak height on a PES spectrum indicate?
The number of electrons in that energy level (subshell).
What does the peak position on a PES spectrum indicate?
The energy level (binding energy) of the electron.
What is the effect of shining light with a frequency below the threshold frequency on a metal?
No electrons are ejected.
What is the effect of increasing the intensity of light with a frequency above the threshold frequency in the photoelectric effect?
More electrons are ejected, but their kinetic energy remains the same.
What does a higher binding energy in a PES spectrum indicate about an electron?
The electron is closer to the nucleus.
Differentiate between binding energy and kinetic energy in PES.
Binding Energy: Energy required to remove an electron. Kinetic Energy: Energy of the ejected electron after removal.
