WHY DO ATOMS COMBINE
The atoms of Noble gases have stable (ns

, np

) configuration, there octet duet in the case of Helium is complete therefore they do not combine.
Atoms of other elements combine in order to complete their respective octet (attain 8 electrons in the valence shell).
They try to complete their octet either by gaining/losing /sharing electrons.
