In the context of a battery holding electrons which carry energy, which we use, what would be the maximum amount of energy that an electron can hold? On what parameters is the energy carried by an electron dependent? Is an electron relating to an atom of one element different from an electron belonging to the atom of another element? Is the capability to hold energy in anyway depend on the atom to which the electron belongs

Thanks for your help. Could you please clarify if this idea is correct? Each pixel can be as tiny as an atom, Each atom of a photographic film undergoes a chemical reaction based on the energy absorbed by it and thus gives a specific color Since assessing the energy absorbed by each atom of the sensor plate is not practically possible, the energy absorbed by a certain area of the plate (or all the atoms in the area) is used to identify the color which would therefore be the combined/average effect of the color relating to all the atoms in that area This is the reason we can say that the photo taken using a digital camera cannot be an equivalent of the photo taken using film camera.

Is it the electron that is absorbing the photon or the atom as a whole ?

With reference to light falling on a camera sensor, if each unit of area on the sensor is the size of the impact area of a single ray (not sure if a single ray can be thought of as an arrow making a hole on impact) ... then into how many units can the sensor be divided ... trying to know the theoretical limit of the mega pixels photo that can be captured using a certain size sensor. I am only a science enthusiast and not a professional. Any kind of explanation for a lay man would be helpful. Thanks in advance.
