Questions and Answers

What is the principal focus of the quantum theory of atoms in molecules (QTAIM)?

  • The observable electron density distribution function (correct)
  • The behavior of electrons within atoms
  • The energy levels of electrons in molecules
  • The interaction between protons and neutrons

According to QTAIM, how is molecular structure revealed?

  • By the quantum spin of the electrons
  • By the total number of electrons in the molecule
  • By the arrangement of atoms within the molecule
  • By the stationary points of the electron density and the gradient paths (correct)

What drove the development of QTAIM?

  • The need to understand the behavior of electrons in molecules
  • The desire to classify and predict chemical reactions
  • The study of electron configurations in crystals
  • The assumption that atoms and bonds should have a well-defined physical basis (correct)
