In the long or modern form of the periodic table, the element in the periodic table have been divided into four blocks, `s-p-d`-and `f`-. Each period begins with the filling of new energy shell. Two series of `f`-block elements are placed at the bottom of the periodic table. The element with `Z=113` has been discovered. Its block, group number, period and ourershell electronic configuration areA. `s`-block, group `2`, period `7,7s^(2)`B. `p`-block, group `13`, period `7,7s^(2)7p^(1)`C. `p`-block, group, 13`, period 6,6s^(2)6p^(1)`D. `d`-block, group `12`,period `6,5d^(10), 6s^(2)`

Answer» Correct Answer - B
`Z =113` means group `13`, and it is `p`-block, and `7thy` period. Therefore, electric configuration is `7s^(2)7p^(1)`.
