Highly energetic electrons are bombarded on a target of an element containing `30` neutrons. The ratio of radii of nucleus to that of Helium nucleus is `141//3`. The atomic number of nucleus will be.
Highly energetic electron are bombarded in a target of an element containing 30 neutrons Tne ratio of nucleus to that of Helium nucleus is (14)^(1//3) . Find (a) atomic number of the nucleus (b) the frequency of k_(a) line of the X- rays producted (R = 1.1 xx 10^(7) m^(-1) and c = 3 xx 10^(8)m//s)
The ratio of the radii of the atom to the nucleus is
If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3 , then the atomic number of this nucleus is
If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3, then the atomic number of this nucleus is
