If IUPAC name of an element is “unununium” then correct statement regarding element is that:
 

“Unununium” : At. number = 111
 It is a transition element. Period number = 7th; Group number = 11 ;

Hint : Z= 104-118…..Z-82 gives an element belonging to same group….111-82=29….Z=29 is Cu ;

Alternate way….Z=104-111…..last two digits give group number of the element….111 belongs to 11^th (‘Cu’ group) ;
