Boron (B)
Silicon (Si)
Germanium (Ge)
Arsenic (As)
Antimony (Sb)
Tellurium (Te)
Polonium (Po)
Two metalloids with symbols not based on English names are antimony (Sb) and germanium (Ge). Their symbols are derived from their Latin names: stibium for antimony and germania for germanium.
The six commonly recognized metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.

where metalloids fit into the properties
Those elements are called metalloids. They have properties that are intermediate between metals and nonmetals.
Metalloids when used is electronics are called semiconductors.
The major categories of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are usually not shiny, brittle, and poor conductors. Metalloids share properties of both metals and nonmetals.
The semiconductors are found primarily in the transition metals groups and are referred to as metalloids.
Elements that have properties of both metals and nonmetals are classified as metalloids. Metalloids have properties that are intermediate between metals and nonmetals, such as being able to conduct electricity but not as effectively as metals. Examples of metalloids include silicon and arsenic.
To accurately answer your question, I would need to know which specific elements you are referring to. Generally, in the periodic table, metals are found on the left and center, nonmetals are on the right, and metalloids are along the zig-zag line separating metals and nonmetals. If you provide the names or symbols of the elements, I can help determine how many are metals, nonmetals, and metalloids.
metalloids
Metalloids are natural chemical elements.
