Nuclear Fission of U-235
Thermal Neutrons - These are slow moving neutrons. Slow moving neutrons are used to bring about the fission reaction. If we use fast moving neutrons, it will not be in contact with the fissionable material for sufficient time to bring about the fission reacti..
Stable Nuclides
Since the positive protons in the nucleus repel each other, neutrons are required to bind the nucleus together. For lighter elements, the number of protons and neutrons are approximately equal. As the number of protons increases the force required to hold the nucleus together i..
Nuclear Chemistry
Atoms contain three fundamental particles namely electrons, protons and neutrons. Protons and neutrons constitute the nucleus whereas electrons are present in the extra nuclear region of the ato..

Isotones
The atoms of different elements, which have the same number of neutrons but different atomic numbers, are called isotone..
Control Rods
To control the fission reaction, rods made of cadmium or boron is suspended between the fuel rods. These rods can be raised or lowered and thus check the reaction by absorbing the right number of neutrons. Hence they are called control rods. When the control rods are completely inserted ..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
Tutor was very thoughful and considerate. She made sure that I understood the concepts every step of the way.
It was not easy for me keep up pace with my school, so my Mom asked me to join here. I am performing much better at school now.
I was searching internet for neutrons and reached this site and I found out they offer tutoring at such a low price.
