Detailed explanation-1: -Because carbon has four electrons in its valence shell, it is able to form four covalent bonds with other atoms.

Detailed explanation-2: -Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.

Detailed explanation-3: -Answer and Explanation: Carbon is an essential building block of organic molecules. This is because it has a unique molecular structure that allows it to form many strong bonds with itself and other crucial elements. It is typically combined with hydrogen to form hydrocarbons.

Detailed explanation-4: -Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. This property is called the catenation.

Detailed explanation-5: -Carbon is in group 4 of the periodic table, therefore it has 4 valence electrons in its outer shell. A full outer shell of electrons consists of 8 electrons. Consequently, carbon must have 4 pairs of electrons to obtain a full outer shell of electrons. This is achieved by having four covalent bonds to become stable.
