Which of the following best defines the ground state of an atom?
A
The state in which all electrons are paired.
B
The arrangement of electrons in the lowest possible energy levels available.
C
The arrangement of electrons in the highest possible energy levels.
D
The configuration where the atom has a positive charge.
Verified step by step guidance1
Understand that the ground state of an atom refers to the most stable arrangement of electrons.
Recall that electrons occupy energy levels or orbitals around the nucleus, and these levels have different energies.
Recognize that the ground state is the configuration where electrons fill the lowest available energy levels first, following the Aufbau principle.
Note that pairing of electrons or the charge of the atom does not define the ground state; rather, it is about minimizing the total energy by occupying the lowest energy orbitals.
Therefore, the ground state is best defined as the arrangement of electrons in the lowest possible energy levels available.
