A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry. Metalloids are elements from the periodic table with properties that lie between metals and non-metals. The following ScienceStruck article will cover some information related to metalloids. The first person to come up with a periodic table of elements was Dmitri Ivanovich Mendeleev, a Russian chemist. He came up with the first version of Metalloids.

Germanium (Ge): Atomic number 32. Arsenic (As): Atomic number 33. The elements commonly classified as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. The status of polonium and astatine is not settled. Most authors recognise one or the other, or both, as metalloids; Herman, Hoffmann and Ashcroft, on the basis of relativistic modelling, predict astatine will be a monatomic metal.
