Answer:
1.Carbon is small and has four valence electrons; these factors combine into a unique structure that allows it to easily make a chain of carbon atoms. It creates covalent bonds — the strongest bonds between atoms. A covalent bond is one where atoms share electrons to form a bond.
2.But what makes carbon unique is that it can bond with other carbon atoms to create long carbon chains and rings. No other element is capable of forming molecules as large and complex as carbon based molecules (think about it—without carbon chains and rings, there could be no DNA!)
3.Because the carbon-carbon bond is stronger than the silicon-silicon bond, carbon compounds stay together in water while silicon compounds break apart. Besides this, another probable reason for the dominance of carbon-based molecules on Earth is the abundance of oxygen.
