Question:

$\text{Elements with an electronic configuration}$ $1\text{s}^2 2\text{s}^2 2\text{p}^6 3\text{s}^2 3\text{p}^6 3\text{d}^{10} 4\text{s}^2 4\text{p}^6 4\text{d}^{10} 5\text{s}^2 5\text{p}^3$ $\text{belong to the group:}$

Options:

1. $3^{\text{rd}}$
2. $15^{\text{th}}$ (Correct)
3. $17^{\text{th}}$
4. $2^{\text{nd}}$

Solution:

$\text{HINT: The outer electronic configuration is}$ $5\text{s}^2 5\text{p}^3$\n\n$\text{Explanation:}$\n\n$\text{The outer electronic configuration is}$ $5\text{s}^2 5\text{p}^3$ $\text{which is resemble to p block elements general electronic configuration that is}$ $\text{ns}^{1-2}\text{np}^{1-6}$. $\text{Also the differentiating electron enters in p-sub shell, hence, it is a p-block element and for p-block element, the group is determined as the total number of electrons present in outer shell.}$\n\n$\text{The outermost shell contains 5 electrons and}$ $15^{\text{th}}$ $\text{group elements contains 5 electrons in its outermost shell. Hence it is belong to}$ $15^{\text{th}}$ $\text{group.}$
