Question

Quizplus · Accepted Answer

The configuration given describes the ground state of Boron (B) which has the electron configuration 1s2 2s2 2p1. The notation used in the configuration given represents the molecular orbitals formed by combining the atomic orbitals of the different atoms involved in the molecule. In this case, there is only one atom (Boron) so the molecular orbital description represents the electron configuration of the atom in its ground state. Therefore, the correct answer is C which corresponds to Boron (B).
