Everything should seem like a piece of cake when you're first learning it. Why don't you want this basic information to be easy for students? I agree complex particle physics is hard. If a student understands the basics and likes it, they'll go on later to study the more complex details--maybe they'll become a particle physicist! But if they hate it when they first learn it because it's so impossible to understand, I guarantee they'll *never* learn more.

@kaustavsengupta8757
5 жыл бұрын
I know it's kinda late to answer but I will try to give answer as short and easy as possible. Well in late 1900 scientist were curious about what are the forces and how they interact with each other. With loads of excellent contribution of various scientist it was determined that in our universe 4 force are present i.e 1. Strong attraction force(nuclear force) , 2. Gravitational force, 3. Electromagnetic forces and last but not least is 4. Weak nuclear force. As per you question alpha particles kicked out of neutrons is because of weak nuclear force. Let me explain every element consistent of proton and neutrons, since all positive charge always repel each other so atom nucleus can't stable right??..No here comes the neutrons to save, you can think of neutrons as charge less but it also acts as cushion so that protons can stay together without rupturing the atoms nucleus. As the heavy the element goes so does the number of protons increases as well as neutrons too. Now comes the trick, there are sometimes when so much positive charge is condense into small space(atom nucleus) that it tend to become unstable due to repulsive force of proton. Since all things in the universe follows law of conservation of energy, to stabilize itself atom nucleus realease energy in form of radioactive (alpha particles, beta, or gamma). Fun fact take example of Uranium. We know Uranium have 2 major isotopes U238 and U-235. U-238 is relatively much stable than latter as it have more neutrons i.e more cushion and glue (stability), where as U-235 have 3 neutrons less and since less cushion and more positive-positive repulsive force which leads to its higher instability and high radioactive. Hope this answers your questions

I will advise you to go and check out "Critical Nuclear Mass" on KZitem or Google. You will come your answers. As far as my interest is concern, yes I have master in molecular biology and we all the time uses small radioactive isotopes to carry out study experiment. If you really want to know how molecular biologist use radioactive isotopes then I will suggest you watch experiment "Hershey-Chase Bacteriophage Experiment" as it is basic of radioactive experiment carryout inside the cell body Moreover python is great for data analysis and for its predictive method machine learning, so we try to use this to effectively collect data of amino acid and other chemical signal and try to make a predictive it's movement through python libraries.

@ekodaoriginals7104
6 жыл бұрын
Pragyan Pandey protons cancelling out means its losing its paraffin wax identity (??!) cuz proton is what that is the most fundamental particle of an atom and if it gets discharged, the wax perhaps turns into something else rather than wax. Here electrons were not shot out therefore, there won't be filling up of any K shell and turn into noble gas or something. Besides, wax is a hydrocarbon?
@ekodaoriginals7104
6 жыл бұрын
That's a smart question, even I wonder, how could he become so sure that it was neutron shooting out, not proton cuz proton-proton repulses and there's a very chance that if protons are shot out then it's gonna have the same action done by neutron kicking out the protons. And the second question of yours, since wax was losing its protons I think it's gonna turn into some other element or at least so like it as proton gives an atom its identity. But again, since it's a complex hydrocarbon, I can't be so sure about it and perhaps, it converts into some other hydrocarbon.

Two things If the particles that were coming from Beryllium did not have a charge how was Chadwik so sure of something coming out?? Was there a sound or some other thing that he was observing?? Geiger counter may be... Second, If photons with no mass can eject an electron ( in photo electric effect) why cant a gama ray do the same with proton? Was there something else.... If a tiny particle hits a massive particle, the tiny particle will be reflected back.... But then how was Chadwick sure of no reflection without observing it? But yes, when a ball strikes to another ball of same mass, it transfers nearly all momentum to the other. Then on weighing Hydrogen and Helium.. This is probably based on the fact that 1 liter of H2 and He will have same number of molecules...but how was that verified without weighing....??

about the gamma ray and proton thingy, because electrons are leptons too and have close to no mass, they can be ejected by photons? Whereas protons were massive and had to be hit by something of similar mass. Besides, they probably thought waves couldn't hit particles since the hypothesis of earlier experiments discovering subatomic particles all assumed a particle was hitting another particle, not a wave (probably thought of as a force) pushing a particle. Just my educated guess :P

One more thing to add is that if there are 2 electrons in K shell then it will complete it's K shell and situation will be really confusing. Other thing is that the electron has already jumped in L shell without completing it's K shell which is against the laws of Bohr's atomic theory. Therefore your diagram is wrong.
