Which of the following is true of carbon?

Carbon can bond with other carbon atoms, sharing a maximum of eight electrons.

Carbon has a very low melting point because C-C bonds are weak.

Carbon can form single, double, or triple bonds with another carbon atom.

None of the above.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

The answer is "Carbon can form single, double, or triple bonds with another carbon atom."
Carbon atoms has 6 electrons, therefore #1 is incorrect
And carbon bonds usually increase the melting point of molecules. #2 is incorrect.

Answer : The correct option is, Carbon can form single, double, or triple bonds with another carbon atom.

Explanation :

Carbon is a non-metal that belongs to group 14 and period 2. The atomic number of carbon is, 6.

The electronic configuration of carbon is, \(1s^22s^22p^2\)

That means, carbon has 4 valence electrons. So, carbon can bond with another carbon atoms by sharing a maximum of four electrons.

And, carbon can also form single, double, or triple bonds with another carbon atom.

The carbon has high melting point because carbon-carbon bonds are strong. That means, the carbon atoms are held together by strong covalent bonds that requires high temperature to break the bonds.

Hence, the correct statement is carbon can form single, double, or triple bonds with another carbon atom.
