To which of the periodic table does the last number of following series belong?
a. `._(94)Pu^(239)` b. `.(58)_Ce^(140)` c. `._(84)Po^(218)`

Text Solution

Verified by Experts

`._(94)Pu^(239)` belongs to actinide series, hence it is present in third group.
b. `._(58)Ce^(140)` belongs to lanthanide series, hence it is present in third group.
c. `._(84)Po^(218)` belongs to `VI` group.
