Verified step by step guidance1
Understand that the question asks for the term that describes how electrons are arranged in an atom.
Recall the definitions of the given terms: 'Isotope' refers to atoms of the same element with different numbers of neutrons; 'Atomic number' is the number of protons in the nucleus; 'Valence shell' is the outermost electron shell of an atom.
Recognize that 'Electron configuration' specifically describes the distribution of electrons among the various atomic orbitals and energy levels in an atom.
Therefore, identify that the term 'Electron configuration' correctly refers to the arrangement of electrons in an atom.
Summarize that electron configuration provides detailed information about which orbitals electrons occupy, their energy levels, and how they are arranged around the nucleus.
