When Were Metalloids First Used?
Antimony, one of the earliest metalloids recognized, was utilized in ancient Egypt both as cosmetics and as a dye for painting, but it wasn’t formally classified as a metalloid until the 1500s. During the Middle Ages, arsenic gained popularity, likely first isolated by the German physician Albertus Magnus around 1250, and used primarily as a pigment before its toxicity was acknowledged. Silicon, another significant metalloid, was discovered by Swedish chemist Jöns Jacob Berzelius in 1823. The production of commercially available semiconductors began in 1954, marking a significant milestone in technology.
Metalloids
Metalloids are the elements in the Chemistry Periodic Table whose properties lie in between those of metals and non-metals. All the elements in the periodic table are classified into three categories namely Metals, Non-Metals, and Metalloids. Elements in the periodic table(an arrangement of different elements in order of their increasing atomic number) for the study of their properties, nature, and reaction with other elements.
