Here's why:
* Hydrogen atoms are simple: They consist of one proton (positive charge) and one electron (negative charge).
* Electrostatic attraction: Opposite charges attract. The positive nucleus of one hydrogen atom is drawn to the negative electron cloud of the other hydrogen atom.
* Covalent bonding: This attraction results in a covalent bond where the two hydrogen atoms share their electrons, creating a stable molecule (H₂).
