Hydrogen atoms, each having one electron in its K shell, share their electrons to form a molecule of hydrogen (H2). This allows each hydrogen atom to attain the electronic configuration of the nearest noble gas, helium.
Describe the formation of the simplest molecule, hydrogen (H2), through electron sharing.
Share
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.
