Create the Lewis dot structure for germanium and discuss its semiconductor properties.

Germanium (\(\text{Ge}\)) is a chemical element with atomic number 32, belonging to Group 14 (IVA) of the periodic table. It shares this group with carbon (\(\text{C}\)), silicon (\(\text{Si}\)), tin (\(\text{Sn}\)), and lead (\(\text{Pb}\)). As a Group 14 element, germanium has four valence electrons, which play a critical role in its chemical bonding and semiconductor properties.

Step-by-Step Solution for the Lewis Dot Structure of Germanium

1. Determine the Number of Valence Electrons

Germanium is in Group 14, which indicates it has four valence electrons. The electron configuration of germanium is:

\[[\text{Ar}] \, 3d^{10} \, 4s^2 \, 4p^2\]

The valence electrons are the electrons in the outermost shell (4s and 4p orbitals), totaling four electrons.

2. Drawing the Lewis Dot Structure

The Lewis dot structure represents valence electrons as dots around the element's symbol. For germanium (\(\text{Ge}\)):

- Step 1: Write the symbol \(\text{Ge}\).

- Step 2: Place four dots around the symbol, representing the four valence electrons.

The dots are placed singly on each side (top, bottom, left, and right) to represent the availability of these electrons for bonding.

\[
\begin{array}{c}
\, \, \cdot \\
\cdot \, \text{Ge} \, \cdot \\
\, \, \cdot \\
\end{array}
\]

This structure illustrates that germanium can form up to four covalent bonds with other atoms, sharing its valence electrons.
