Which of the following points are correct regarding the electronic configuration? A. It is the arrangement of electrons in the shells of an atom. B. It is the arrangement of electrons in the subshells. C. It is the arrangement of electrons in the orbitals of an atom.

Which of the following points are correct regarding the electronic configuration? A. It is the arrangement of electrons in the shells of an atom. B. It is the arrangement of electrons in the subshells. C. It is the arrangement of electrons in the orbitals of an atom. Correct Answer A, B, C all three

The correct answer is A, B, C all three.

Key Points

• The electronic configuration of an atom is the representation of the arrangement of electrons in the shell, sub-shell, and orbitals in an atom.
• So A, B, C all three statements are true.

Additional information

• Element's electron configuration is the arrangement of the electrons in the shells.
  • There are a few guidelines for working out this configuration: Each orbital can hold only two electrons.
  • Electrons that occur together in an orbital are called electron pairs.
  • Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.
  • According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.
