Carbon atoms can form chains and branches with each other, and other atoms can attach to these.
Why is carbon said to provide a “backbone” in many molecules?(1 point)
Responses:
Carbon atoms have half-full shells of electrons, allowing electrical signals to pass through them easily.
Carbon atoms have long narrow shapes, allowing many other atoms to attach to them.
Carbon atoms have full shells of electrons, allowing electrical signals to pass through them easily.
