Explain
Duplet rule for the formation of hydrogen
Advertisements
उत्तर
Elements tend to combine with one another to attain the stable electronic configuration of the nearest inert gas.
Hydrogen
A hydrogen atom has one electron in the valence shell which shares with another hydrogen atom having one electron to complete its duplet state, i.e. two electrons in the valence shell and resulting in the formation of hydrogen.
