It is not meaningless

Classical Mechanics Level 2

Select the most appropriate statement.

Both electrons and molecules do not have any colour Electrons do have a colour but under certain set of conditions Electrons dont have a colour but molecules can have It is meaningless to define a property like colour to any of electrons,protons or neutrons Both molecules and electrons have a colour

I am sure ,you would have thought twice thrice before answering, I believe the problem demands that! Anyways,to the solution. See first a colour is something that our eye interprets based on the light energy it recieves,moreover you see an object colored when the object reflects the color it is colored(or percieved to be) the most. And electrons are just too small to reflect the size of wavelengths that visible region has.so,they cant have a colour . But certain molecules that are big enough can reflectthe wavelengths so it is possible for them to have a colour.pls i would love to see your comments on this topic.

n o t e : \Large note: And pls dont forget to reshare in case you liked the eccentricity of the problem :)

I think that electrons absorb the light energy and release it back by electron transition .

Hi siddharth,can you please be more specific whether it is a doubt or it is a report or simply an act of initiating a discussion , anyways to your point, you are absolutely right in your say. Electrons absorb and emit energy in the process of their transitions inside an atom. But the same doesn't conclude that they are"colored " that way, see that the electrons might absorb different amount of energies and emit different amount (based on transitions it makes, maybe just to neighbour shell or maybe jump three four shells), so if this is taken into account to say that electrons are colored because we have recieved energetic photons,it will be simply wrong because you have recieved different wavelengths of those different photons. And so different colors of electrons.,which is not true! And remeber this golden rule : "most things are colored that way, which they reflect the most". And in your higher grades you will read(officially,though i would suggest you read now) electron itself behaves like a wave(de broglie's principle), how bizzare it is to imagine a wave reflecting another wave (light wave,in particular).feel free to extend this discussion/ or ask any doubt :)
