electron with no KE in reality

[Chloe Qiao 4C]

I understand how electrons behave in experiments when energy of the incoming light equals to its threshold energy, but can someone explain what it is like in reality when the ejected electron has no kinetic energy?

[taryn_baldus2E]

If an electron has no kinetic energy, then there was still enough energy in the incoming light to remove the electron from the metal. Because the threshold used up all of the energy, there is no excess or kinetic energy that would allow the electron to move from its current position to another.

The energy would be enough to break the electron away from its atom, but it wouldnt be ejected away from it. So essentially it broke the electron's attraction to the atom but it is still there;.
