Physics 2013 JAMB Past Questions - Question 50: The bond between silicon and germanium is

Correct Answer

A

Explanation

Silicon and germanium are tetravalent. they have four valency electrons. one valence electron is shared with each of four surrounding atoms in a tetrahedral arrangement, forming covalent bond
The bond between silicon and germanium is primarily covalent in nature. Both silicon and germanium belong to Group 14 of the periodic table, which means they have four valence electrons. These electrons are involved in forming covalent bonds with neighboring atoms. In the case of silicon and germanium, they can share electrons to form a covalent bond, resulting in a crystal lattice structure. This bond is relatively strong and contributes to the semiconducting properties of silicon and germanium, making them important materials in electronics and semiconductor devices.
