Carbon shares four pairs of electrons to complete its valence shell (option C).
Based on the electron configuration, the carbon atom has 4 valence electrons or 4 electrons in its outermost shell. It is the presence of these valence electrons that play an important role in forming chemical bonds. Every atom is capable of forming a stable, including the carbon atom.
To achieve stability, this atom needs another 4 electrons by forming covalent bonds. Only the carbon atom is capable of forming 4 covalent bonds to reach the octet state.
The carbon atom (C ) has a unique characteristic with an atomic number of 6 electron configurations, namely the ability to form long C chains. Atom C has 4 valence electrons, which can be covalently bonded with similar atoms or other atoms.
