Current Question (ID: 10558)

Question:

$\text{An element belongs to group 15 and 3}^{\text{rd}} \text{ period of the periodic table. Its electronic configuration would be:}$

Options:

1. $1s^2 2s^2 2p^4$
2. $1s^2 2s^2 2p^3$
3. $1s^2 2s^2 2p^6 3s^2 3p^2$
4. $1s^2 2s^2 2p^6 3s^2 3p^3$ (Correct)

Solution:

$\text{HINT: The element is Phosphorous.}$ $\text{Explanation:}$ $\text{General valence shell electronic configuration of group 15 elements is } ns^2 np^3 \text{ and for third period n=3.}$ $\text{Thus, with electronic configuration } 1s^2 2s^2 2p^6 3s^2 3p^3, \text{ the element is phosphorus.}$
