The metalloids, also known as semi-metals, are placed between metals and non-metals in the periodic table of elements. There are seven elements that are classified as metalloids and placed in Group 13, 14, 15, 16, and 17. They are found in a stair step line that helps differentiate metals from non-metals in this element table.
These elements can be categorized as being either metals, nonmetals, or metalloids. The location of the element on the Periodic Table yields some clues about whether an element is a metal, a nonmetal, or a metalloid.

Since we identified {Sn 10 [Si(SiMe 3) 3] 4} 2− 7 as an ideal candidate for such reactions, we present a further step in the understanding of metalloid tin cluster chemistry. In contrast to germanium chemistry, ligand elimination seems to be a major reaction channel, which leads to the more open metalloid cluster {Sn 10 [Si(SiMe 3 ) 3 ] 3 } − 9 , in which the Sn core is only shielded by

Metalloids are a group of elements that run from Boron to Polonium in the periodic table that bridge the metals and non metals. They are a group of elements that have a range of properties that are not quite metals and not quite non metals. There is not one agreed specified definition for metalloids.
