In modern IUPAC notation, it is called group 14. In the field of semiconductor physics , it is still universally called group IV . The group is also known as the tetrels (from the Greek word tetra , which means four), stemming from the Roman numeral IV in the group name, or (not coincidentally) from the fact that these elements have four ...

The other group 14 elements have a lower tendency to catenate. Hydrosilicons ( binary silicon-hydrogen compounds ), a silicon analogs of hydrocarbons, such as silanes Si n H 2 n +2 are known for n = 1–8, in which thermal stability decreasing as n increases (e.g. silane SiH 4 and disilane Si 2 H 6 ), as are cyclosilanes (e.g. cyclopentasilane ...
