Shared electrons create a stable configuration for each atom involved in the bond, leading to the stability of the molecule as a whole.

Shared electrons create a stable configuration for each atom involved in the bond, leading to the stability of the molecule as a whole.

After forming H2, each hydrogen atom attains the electronic configuration of helium, which has two electrons in its K shell, making it more stable.

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.

Sharing electrons allows atoms to attain the noble gas configuration in their outermost shells, making the molecules more stable.
