Answer
Hydrogen is a non-metal and has 1 valence electron, so in order to attain a stable duplet electronic configuration, it tries to gain one more electron. As both the combining atoms are one electron short, therefore, none of the two atoms are in a position to donate. Hence, they share 1 valence electron and get a stable duplet configuration.
