The distance between the nuclei of two carbon atoms in its elemental form is 154pm.
What is distance?
Distance is a numerical measurement of how far the objects or points are. It is the actual length of the path travelled from one point to another.
What is nuclei?
Nuclei is a plural form of nucleus. The nucleus is a collection of particles like protons, which are positively charged and neutrons, which are electrically neutral.
The carbon–carbon (C–C) bond length in diamond is 154 pm. It is the average length for a carbon–carbon single bond and it is also the largest bond length that exists for ordinary carbon covalent bonds.
Therefore, the distance between the nuclei of two carbon atoms in its elemental form is 154pm.
Hence, option b is the answer.
