Uranium is atomic number 92 - this means it has 92 protons - which in a neutral atom means it also has 92 electrons. 235 and 238 are the mass numbers (or nucleon number) of two of its isotopes. The neutron number = the mass number - the atomic(proton) number.
So just subtract 92 from both 235 and 238 to get your answer. More.
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.
