Metalloids were first identified as a group of elements with properties between metals and non-metals in the mid-19th century by chemist Baron Ernst von Reichenbach. However, the concept of metalloids as a distinct group of elements was further developed in the early 20th century by chemist William Crookes.

What are the 8 metals metalloids and nonmetals that the alchemists discovered and what are their element symbols?
For the alchemic symbols see this list.
How many types of element are there in periodic table?
Three: nonmetals, semimetals (or metalloids), and metals.
What class of metal elements are semi conductors?
The semiconductors are found primarily in the transition metals groups and are referred to as metalloids.
What is classification for the elements that have properties of both metals and non metals?
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.
Are metalloids space-age synthetic elements?
Metalloids are natural chemical elements.
