Current Question (ID: 20912)

Question:

$\text{The correct electronic configuration of an element that is just above the 4th period and belongs to the 16th group:}$

Options:

1. $4s^23d^{10}4p^4$
2. $2s^22p^4$
3. $3s^23p^4$
4. $5s^25d^{10}4p^4$

Solution:

$\text{Hint: The element belongs to group 16th and the period is third}$ $\text{The period above 4th period is the 3rd period. The element belong to 16th group is as follows:}$ $\begin{array}{ccc} \text{16th group} & \text{EC} \\ \text{2nd} & \text{O} & 2s^22p^4 \\ \text{3rd} & \text{S} & 3s^23p^4 \\ \text{4th} & \text{Se} & 4s^24p^4 \\ \text{5th} & \text{Te} & 5s^25d^{10}4p^4 \end{array}$ $\text{The element below the third period of the 16th group is sulphur. The electronic configuration is } 1s^22s^22p^63s^23p^4.$ $\text{Hence, the correct option is the third option.}$
