Chapter 5.3, Problem 24PP

Solution

Interpretation : The element used as part of semiconductors and used in various alloys is to be identified.

Concept Introduction : The most basic type of matter is an element that has its own set of characteristics. The electron configuration of an atom refers to how its electrons are arranged.

The ground-state electron configuration $\left[\text{Kr}\right]5s^{2}4d^{10}5p^1$ is silver, which is part of semiconductors and various alloys.

The electrons in an atom often assume the configuration that provides the atom with the lowest energy possible since high-energy ones are less stable than low-energy systems.

The term "ground-state electron configuration" refers to the arrangement of electrons in an element that is the most reliable and lowest in energy.

The Aufbau principle, Hund's rule, and the Pauli exclusion principle are three laws or principles that specify the possible arrangements of electrons in an atom's orbitals.

The count of the electronic configuration is given as:

  $\begin{array}{c}\left[\text{Kr}\right]5s^{2}4d^{10}5p^1=36+2+10+1\\ =47\end{array}$

The element with atomic number 47 is silver.

Silver finds its application in alloys and semiconductors.
