Semi-metals have free electrons which can conduct elecricity.
The most useful property of semimetals is their intermediate electrical conductivity, which allows for applications in electronics and semiconductors. Semimetals also exhibit interesting properties such as Dirac cones and topological insulating behavior, making them valuable for research in quantum materials and physics.
The property that makes semi-metals useful as "switches" is that their varying ability to conduct electricity.
Semimetals are typically found in the periodic table, primarily in groups 13 to 16. Common examples include elements like arsenic, antimony, and bismuth. They possess properties of both metals and nonmetals, making them useful in various applications such as electronics and materials science. Semimetals can also be found in certain compounds and alloys.

Why were stone tools useful? Both electronics & stone tools allow us to do things we could not do without them or could do but with much less efficiency.
Nickel is a conductor of electricity due to its atomic structure that allows for the easy flow of electrons. This property makes nickel useful in various applications in electrical engineering and electronics.
This is a chemical process used to make high purity and high quality solid materials. It is used frequently in the electronics industry and is also useful in making synthetic diamonds.
Humans use gold for a variety of reasons, not the least of which is the jewelry industry. Gold has historically been used as currency or as a backing for currency. Gold is also used in electronics and audio components.
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.
If it is a guard dog it guards property, that is useful.
