Helium
Atomic no : = 2
Electrons = 2
Electronic Configuration = 2,0
Helium has valency zero because its K shell is filled and it does not need to react with other elements to gain or lose or share electrons.
Thus , its Valency or combining capacity of Helium is zero.

Ernst Rutherford is the scientist who proved that the nucleus of an atom is positively charged in his Gold Foil experiment .
