Group 14 - The Carbon Group

Elements in this group have 4 electrons
in their outer shell.  This allows them to
bond to other atoms in a remarkable
number of ways.  
Carbon is the basic
element of all life on our planet.  (In
geeky SciFi shows they sometimes call
humans
carbon-based life forms)  
Silicon is a metalloid that is the basis for
all of the 'chips' that make up computers
and numerous electronics.
