Then in 1869, as a result of an extensive correlation of the properties and the atomic weights of the elements, with special attention tovalency(that is, the number of single bonds the element can form), Mendeleev proposed the periodic law, by which “the elements arranged according to the ...
From the statement, we can see that the outermost configuration is the same as the p- block elements and thus, an element with atomic 114 is a p- block element.- The element uranium having the atomic number Z = 92 have been irradiated with many slow neutrons ...
