Question

according to the textbook what is the definition of \electron configuration\. *

a visual model of the most likely locations for electrons in an atom

the arrangement of electrons in the orbitals of an atom

when all the atoms of an electron have the lowest possible energies

a region of space around the nucleus where an electron is likely to be found

Explanation:

To determine the correct definition of "electron configuration", we analyze each option:

• The first option describes an electron cloud model, not electron configuration.
• The second option, "the arrangement of electrons in the orbitals of an atom", matches the definition of electron configuration.
• The third option refers to the concept of a system in its ground state (lowest energy), not electron configuration.
• The fourth option defines an orbital, not electron configuration.

Answer:

B. the arrangement of electrons in the orbitals of an atom
