(i) How do the electronic configurations of the elements with Z = 107 -109 differ from one another?
(ii) Rn (Z = 86) is the last noble gas discovered. Predict what will be the atomic number of the next noble gas to be discovered. Write its symbol.

(i) Element with Z = 107 has five, Z = 108 has six while Z = 109 has seven 6^-electrons. Thus, these elements differ in the number of electrons in the 6^-subshell.
(ii) 118, UUO
