Question

Carbon has four electrons in its outer shell. Why does this make it important to life?(1 point)
Responses

The outermost shell is full, making it a stable element that can bond to water.
The outermost shell is full, making it a stable element that can bond to water.

The outermost shell can only bond with hydrogen and other carbon atoms.
The outermost shell can only bond with hydrogen and other carbon atoms.

The outermost shell can form up to four covalent bonds and this allows it to form biomolecules.
The outermost shell can form up to four covalent bonds and this allows it to form biomolecules.

The outermost shell never fills making it unstable and unable to bond to other carbon molecules.
The outermost shell never fills making it unstable and unable to bond to other carbon molecules.

GPT-4o mini · Answer

The correct response is: **The outermost shell can form up to four covalent bonds and this allows it to form biomolecules.** This property of carbon is crucial for the complexity and diversity of biological molecules, as it can bond with a variety of other elements, including hydrogen, oxygen, nitrogen, and other carbon atoms, enabling the formation of a wide range of organic compounds essential for life.
