Do protons have less mass then neutrons electrons and nucleus?

Protons are part of the nucleus, so they have less mass than the nucleus (except in the specific case of hydrogen, where the nucleus is a single proton so they have the same mass) Electrons are much less massive than protons. It would take 1836 electrons to equal the mass of one proton Neutrons are very slightly more massive than protons, by just about the mass of an electron. They're close enough that they're generally treated as having essentially the same mass.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
