Q: What is the work function of a metal?
Solution:
The work function is the minimum energy required to remove an electron from the surface of a metal.
Steps: 4
Show Steps
Step 1: Understand that metals have electrons that can move around.
Step 2: Realize that to remove an electron from a metal, you need to provide energy.
Step 3: The work function is the specific amount of energy needed to take an electron away from the metal's surface.
Step 4: This energy is the minimum required; if you provide less, the electron will not leave.
