Answer»

Solution :Z = 114 which is situated between 86 nad 118.
` :. ` Its PERIOD = 7 .

If `Z = 114 `, its Group is 14.
ELECTRONIC Configuration :
`[RN]^(86)5f^(14)6d^(10)7s^(2)7p^(2)`
Last`e^(-) ` is in 7p
`:. ` It is P-Block element.
`{:(-,6d" contain ",10),(-,7s" contain ",2),(-,7p" contain ",2),(,,bar(14)):}`
`:. ` It is PRESENT in `14^(TH)` Group.
