9. James Chadwick added the finishing touch to the Atomic Theory.What sub-atomic particle did Chadwick discover?What is the charge on this particle and where is it located in the atom? ** The Rutherford-Bohr model of the atom is still not entirely correct.Currently, the“Quantum-Mechanical ...
The pattern of bars is called mass spectrum and each bar corresponds to a particular mass.The bar produced by the heaviest ion (the one with the highest mass/charge)gives the relative formula/molecular mass of the compound.(i)Suggest the name of the sub-atomic particle that must be lost ...
