Describe the formation of the simplest molecule, hydrogen (H2), through electron sharing.

sharing between two hydrogen atoms. Each hydrogen atom contains one electron in its outermost shell. To achieve a stable electron configuration similar to helium, which has a full outer shell, two hydrogen atoms share their electrons. This results in the formation of a covalent bond, where the pair of electrons is shared between the two hydrogen atoms. This sharing satisfies the duet rule, ensuring each hydrogen atom now has a complete, stable electron shell. The resulting H2 molecule exhibits a covalent bond and is the fundamental unit of molecular hydrogen.
