Question

Which key difference between carbon and silicon makes carbon better suited to forming molecules for living things?(1 point)
1. Carbon has a greater atomic mass, allowing for stronger molecules.
2. Carbon has the right number of outer electrons to form a wide range of molecules.
3. Oxidized carbon is a gas at room temperature, rather than a solid.
4. Carbon is a naturally occurring element, so it is readily available.

Answer 1

2. Carbon has the right number of outer electrons to form a wide range of molecules.
