you could also talk about finding the missing mass of neutron in fermi's nuclear fission reaction, finding STRONG nuclear force to compensate the imbalance of electrostatic + gravitation attraction and also one more ^^The role of conservation laws where Pauli's prediction of the Neutrino and Chadwicks discovery of the neutron?
I wrote about how proton= 2u and 1d and neutron = 2d and 1u.Question:
the internal structure of a proton and neutron, did you have to talk about flavour of the quarks or was that extra?
it is a 2 mark question so thats all you probably need. flavour just shows they interact with the strong forceI wrote about how proton= 2u and 1d and neutron = 2d and 1u.
Up has a charge of +2/3 and down has a charge of -1/3 so this determines their charges. Also, down weighs more than up which is why a neutron is heavier than a proton
