- Hydrogen atoms are destabilized during decomposition of the atom.
- Unstable neutrons are not components of the atoms
- All atoms are made up of hydrogen
- The discoverer of the decaying neutron was Robson in 1950 and not Chadwick
The concept of a neutron was the life-belt or sheet anchor for quantum atomic theory. If for an element with atomic number Z, this number represents both the quantity of protons in the nucleus and the number of extranuclear electrons then the nucleus must incorporate chargeless particles because the mass number A is greater than Z. Take for example beryllium: Z = 4, A = 9; A ? Z = 5: the nucleus should consist of 4 protons and of uncharged particles that are responsible for the remaining mass-quantity 5 of the nucleus. So it was conjectured that 5 socalled neutrons are embedded in the nucleus.
Another question for the possibility of the existence of such a nucleus was the problem that the positively charged protons repel each other. The neutron was again the life belt: the claim is that neutrons and protons are bound together by a hypothesized strong nuclear force ? mere words! Why the 2 protons and 2 neutrons of the He-nucleus bind together especially tightly and the 4 protons and 4 neutrons of beryllium-8 do not remain unexplained. How do we get neutrons? ...
