Interpretation: The number of paired electrons in an atom of each element is to be determined.
Concept Introduction: Electronic configurations refer to the arrangements of electrons in different orbitals around atoms' nuclei.
Answer to Problem 58A
There are two paired electrons in the helium element.
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 energy levels and symbols for each sub-level occupied by an electron are written for an atom's electrical configuration.
The given element is helium.
The electronic configuration of helium is
There is only one orbital that can accommodate only two electrons. So, the atoms are filled.
Hence, there are two paired electrons in helium.
