Hi, so I found the work function but how do I find the max number of electrons?

Hi,
To solve this problem, we need to first use the equation work function= Ephoton - KE. Then, to find the the maximum number of electrons that could be ejected, we divide the total energy by threshold energy (which is also known as the work function value you got in the first part of your answer). So total energy/threshold energy = max # electrons that can be ejected.

The work function is the amount of energy required to remove an electron. If each electron requires a certain amount of energy for it to be removed and you have a specific amount of energy total then Total energy/work function should tell you the number of electrons.

E(of photon)=Work function + Kinetic Energy of electrons

The work function is also the amount of energy required for a photon to remove one electron. Therefore, to find the max number of electrons, we must divide the total kinetic energy of electrons by the energy to remove one electron.

We can find the total energy of electrons by using this equation:
KE=1/2mv^2
(v=velocity)

We can find both the work function and energy of photons using the same equation:
E=hv
(v=frequency)
