It has since been applied to any other similarly toxic metal, or metalloid such as arsenic, regardless of density.
It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.
Because of its position in the periodic table, polonium is sometimes classified as a metalloid.
It has been referred to as either a very poor metal, a metalloid, a nonmetal or a near metalloid.
Use of the term metalloid subsequently underwent a period of great flux up to 1940.
During the 1920s the two meanings of the word metalloid appeared to be undergoing a transition in popularity.
The end of this row shows the average number of elements per metalloid list.
A brittle, mildly toxic, rare, silver-white metalloid which looks similar to tin, tellurium is chemically related to selenium and sulfur.
