Questions & Step-by-Step Solutions

What is the minimum energy required to remove an electron from a metal surface with a work function of 2 eV? (2021)
  • Step 1: Understand what a work function is. It is the minimum energy needed to remove an electron from a metal surface.
  • Step 2: Identify the work function given in the question, which is 2 eV.
  • Step 3: Realize that the minimum energy required to remove an electron is equal to the work function.
  • Step 4: Conclude that the minimum energy required to remove an electron from the metal surface is 2 eV.
