(a) The electronic configuration of element `X` is `[Rn]^(86) 5f^(14) 6d^(10) 7s^(2)`
(b) If belongs to d-block as last electron enters in d subshell.
(c ) As number of electrons in `(n-1)d` subshell and valence shell is equal to twelve i.e `10 +2`. So it belongs to group `12`
(d) It belongs to period `7` of the periodic table as principal quantum number of valence sheel is `7 (i.e., 7s^(2))`
