Interpretation: The configuration of the highest occupied energy level for the strontium 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 10STP
The correct option is (C).
Explanation of Solution
Reason for correct option:
The given element is strontium. The
Thus, the filling of electrons takes place in the order s , p , d, and f .
The electronic configuration can be represented as follows:
This can be rewritten as follows:
Thus, the highest occupied energy level is
Therefore, option (C) is correct.
Reason for incorrect options:
The electronic configuration of strontium 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 5. From the electronic configuration, there is one sublevel with this principal quantum number that is
Therefore, options (A), (B), (D), and (E) are incorrect options.
