Solution

The correct option is B $4^{14} 5 d^{10} 6 s^{2} 6 p^{6}$
The last element of the p-block in the 6th period is represented by the outermost electronic configuration is $4 f^{14} 5 d^{10} 6 s^{2} 6 p^{6}$ .

The sixth period, where n equals $6$ , contains $32$ elements and the successive electrons enter the $6 s, 4 f, 5 d$ and $6 p$ orbitals, respectively.

The last element in the p-block in $6 t h$ period is $R n [86]$ .

Hence, option (C) is correct.

(i) Comprehension given below is followed by some multiple choice questions. Each question has one correct option. Choose the correct option. In the modern periodic table, elements are arranged in order of increasing atomic numbers which is related to the electronic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, viz s, p, d, and f.
The modern periodic table consists of 7 periods and 18 groups. Each period begins with the filling of a new energy shell. In accordance with the Aufbau principle, the seven periods (1 to 7 ) have 2, 8, 8, 18, 18, 32, and 32 elements respectively.
The seventh period is still incomplete. To avoid the periodic table being too long , the two series of f-block elements, called lanthanoids and actionoids are placed at the bottom of the main body of hte periodic table
