Answer to Problem 41A
The electronic configuration of the sodium atom is
Explanation of Solution
Electronic configurations refer to the arrangements of electrons in different orbitals around atoms' nuclei.
The Aufbau principle, the Pauli exclusion principle, and Hund's rule are three rules that can be used to determine the electronic configuration of atoms.
The symbol
The
Sodium contains 11 electrons.
The energy levels and symbols for each sub-level occupied by an electron are written for an atom's electrical configuration.
Each sub-level is superscripted with the number of electrons occupied. The number of electrons in an atom is equal to the sum of the superscripts.
The order of orbital filling of the atoms is given as
