Complement of a set
Let U be a universal set, A be any subset of U, then the elements of U which are not in A i.e., U - A is the complement of A w.r.t. U is written as A' = U - A = A c ..
Let U be a universal set, A be any subset of U, then the elements of U which are not in A i.e., U - A is the complement of A w.r.t. U is written as A' = U - A = A c ..Proof:
Every set A is a subset of universal set U since, by definition all elements of A belong to U. Also the null set f A..

In 1936, Neils Bohr suggested that the nucleus might be like a droplet of dense liquid, composed of sub droplets of protons and neutrons. A uranium nucleus is spherical in shape. In this spherical nucleus, protons and neutrons are together because of the delicate balance existi..
(i) The secondary neutrons can be made to escape out of the system.
(ii) The neutrons can be absorbed by substances which are not fissionable. Rods of boron or cadmium have the ability to absorb the desired number of neutrons. This ensures limited number of neutrons to be available for fission. (iii) The speed of t..
Discovery of Neutrons
. Thus the relative mass of such a particle = 1 a.m.u and the absolute mass = 1.6 x10 -24 g. Because of their electrical neutrality, these particles were called neutrons..

Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stab..
