What is the effect of doubling the photon flux of light on whether electrons will be emitted from a metal?

A. Light with greater photon flux is more likely to cause electrons to be emitted than the weaker light.
B. Light with greater photon flux will cause electrons to be emitted with faster velocities than the weaker light.
C. Light with less photon flux must shine for a longer time to cause electrons to be emitted.
D. The photon flux has no effect on whether electrons are emitted or not.

Thank you!

A. Light with greater photon flux is more likely to cause electrons to be emitted than the weaker light.

Explanation:

Doubling the intensity of photo flux will double the number of electrons ejected from the metal surface.However, the kinetic energy distribution will remain the same.The number of photo electrons emitted per second is directly proportional to photo current produced and to the intensity of photon flux of light.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
