Obtain approximately the ratio of the nuclear radii of the gold isotope `""_97^197 "Au"` and the silver isotope `""_47^197"Ag"`.
If neutrons exert only attractive force, why don't we have a nucleus containing neutrons alone?
The atomic mass of Uranium `""_92^238"U"` is 238.0508 u, while that of Thorium `""_90^234"Th"` is 234.0436u, and that of Helium `""_2^4"He"` "is 4.0026u. Alpha decay converts `""_92^238"U"` into `""_92^234"Th"` as, shown below:
`""_92^238"U" -> ( ""_90^234"Th" + ""_2^4"He" + "Energy" )`

A nucleus of mass number A has a radius R such that ______.
A nucleus yYx emits one α and two β particles. The resulting nucleus is ______.
The valance electrons in alkali metal is a:-
James Chadwick, in 1932 studied the emission of neutral radiations when Beryllium nuclei were bombarded with alpha particles. He concluded that emitted radiations were neutrons and not photons. Explain.
Two nuclei may have the same radius, even though they contain different numbers of protons and neutrons. Explain.
What conclusion is drawn from Rutherford’s scattering experiment of α-particles?
