Some science fiction stories refer to planets with silicon-based life forms. Why would science fiction writers choose silicon as an element that could support life?
1. Silicon is in the same group (14) as carbon on the periodic table, and has four valence electrons for bonding just like carbon
2. Silicon can form all of the same organic molecules that carbon does
3. Silicon has more protons than carbon, and therefore it can form stronger chemical bonds in the weightlessness of space
4. Silicon, along with carbon, oxygen and hydrogen, is often found in organic molecules on Earth
