Theories about extraterrestrial life forms whose biochemistries differ radically from those on Earth have given rise to alternative biochemistry, a speculative science that often appears in works of science fiction. Common examples proposed by scientists in this field include life forms that use elements other than carbon to construct primary cellular structures or those that use solvents other than water. Why is the silicon atom considered a possible basis for an alternative biochemical system? Discuss
