Question
Chapter 5, Problem 17STP
Interpretation Introduction
Interpretation:
The correct orbital diagram for beryllium element needs to be determined.
Concept introduction:
According to the Aufbau principle in the ground state, an electron first enters the lowest energy level and further electrons are added to the orbitals with increasing energies.
Expert Solution & Answer
Answer to Problem 17STP
Correct answer: The correct option is B.
Explanation of Solution
Reason for correct option:
According to the Aufbau principle, the electron first enters into the lowest energy level. The options are as follows:
Beryllium contains four electrons and its electronic configuration is
Therefore, the diagram that contains total four electrons is option B.
Conclusion
Reason for incorrect options:
- The total number of electrons is only 2 but in beryllium the number of electrons is 4 thus, option A is incorrect.
C. The total number of valence electrons is 7 but in beryllium the number of electrons is 4 thus, option C is incorrect.
D. The given electronic configuration cannot be true for any element as it does not follow Aufbau principle. Thus, option D is incorrect.
