Interpretation: The configuration of the highest occupied energy level for sulphur element needs to be identified.
Concept Introduction: The electronic configuration represents the arrangement of electrons in atomic orbitals. Here, s , p , d, and f are sublevels in which electrons are distributed. The maximum number of electrons in s , p , d, and f orbitals are 2, 6, 10, and 14.
Answer to Problem 6STP
The correct option is (E).
Explanation of Solution
Reason for correct option:
The given element is sulphur. The
Thus, the filling of electrons takes place in the order s , p , d, and f .
The electronic configuration can be represented as follows:
Thus, the highest occupied energy level is
Therefore, option (E) is correct.
Reason for incorrect options:
The electronic configuration of sulphur is as follows:
The increasing order of energy with respect to principal quantum number is as follows:
Thus, the highest occupied energy level will be with principal quantum number 3. From the electronic configuration, there are 2 sublevels with this principal quantum number that is
Therefore, options (A), (B), (C) and (D) are incorrect options.
