The elements Z = 117 and 120 have not yet been discovered. In which family / group you place these elements and also give the electronic configuration in each case.
Dear Student,
Atomic number = 117
Element = Ununseptium
Electronic configuration = [Rn] 5f14 6d10 7s2 7p5
Group number = 17
Atomic number = 120
Element = Unbinilium
Electronic configuration =[Rn] 5f14 6d10 7s2 7p6 8s2
Group number = 2
Atomic number = 117
Element = Ununseptium
Electronic configuration = [Rn] 5f14 6d10 7s2 7p5
Group number = 17
Atomic number = 120
Element = Unbinilium
Electronic configuration =[Rn] 5f14 6d10 7s2 7p6 8s2
Group number = 2
