Q2 / 160 · AP EAMCET 2018 (24 Apr Shift 1) · Chemistry

Number of completely filled orbitals in xenon atom $(\mathrm{Xe})$ is

A
17
B
18
Correct answer
C
27
D
28

Solution

The electronic configuration of xenon having atomic number 54 is given as: $$ { }_{54} \mathrm{Xe}=1 s^2, 2 s^2 2 p^6, 3 s^2 3 p^6 3 d^{10}, 4 s^2 4 p^6 4 d^{10}, 5 s^2 5 p^6 $$ Thus, the number of completely filled orbital in xenon atom $(\mathrm{Xe})$ is 27.

Hence, the correct answer is option: 'C'.
