Work function of the metal is
- A Maximum possible energy acquired by an electron
- B Equal for all metals
- C Minimum energy required by an electron to just eject from metal surface
- D Maximum energy which is given to electron to move out of metal surface
Answer & Solution
Correct Answer
(C) Minimum energy required by an electron to just eject from metal surface
Step-by-step Solution
Detailed explanation
The work function of a metal is defined as the minimum amount of energy required by an electron to just escape from the metal surface.
It is a characteristic property of the metal and varies from one metal to another.
