You can see this happen in the F2 molecule. Each fluorine atom shares a valence electron with the other fluorine atom. So there is just one covalent bond.

Germanium belongs to family of metalloids.They are also known as semi conductors.
Germanium, symbol Ge, has an atomic number of 32. It is a metalloid in the carbon group.

Elements in Families on the periodic table have similarities. Elements in the same family as iron are magnetic. The air force had a tremendous problem. Traditional lubricants were not working under the stresses their new machinery used. All of their lubricants were carbon based. They looked at the next element in the same family on the periodic table. It was silicon. They made a lubricant based on silicon. It worked fine. The first diodes and transistors were made with Germanium. It is an expensive metal to produce. It is on the periodic table right above silicon. This led to a number of experiments and attempts to produce a transistor using silicone. Finally after many tries, it worked. Inexpensive silicon transistors could replace expensive germanium ones. You wrote your question because silicon is below Germanium on the periodic table.
Because germanium was not known at the time when Mendeleev formulated his periodic table.
