Question:

$\text{Consider the following electronic configuration of an element (P):}$\n\n$[\text{Xe}]4\text{f}^{14}5\text{d}^16\text{s}^2$\n\n$\text{The correct statement about element 'P' is:}$

Options:

1. $\text{It belongs to the 6th period and the 1st group.}$
2. $\text{It belongs to the 6th period and the 2nd group.}$
3. $\text{It belongs to the 6th period and the 3rd group.}$ (Correct)
4. $\text{None of the above.}$

Solution:

$\text{HINT: The period number corresponds to the highest principal quantum number (n) of the elements in the period.}$\n\n$\text{Explanation:}$\n\n$\text{The electronic configuration of lutetium (Lu) is as follows:}$\n\n$[\text{Xe}]4\text{f}^{14}5\text{d}^16\text{s}^2$\n\n$\text{The period number is 6th because the highest n value is 6. The group is 3rd group because all lanthanoids belong to the third period.}$\n\n$\text{Atomic number = 71}$ $\quad$ $\text{Period number = 6th}$ $\quad$ $\text{Group number = 3rd}$
