Question
Explain the following briefly:
Helium does not form $He_2$​​​​​​​ molecule
✓

Answer

Helium does not form $He _2$ molecule as it has its outermost shell complete i.e. two electrons in its valence shell. Due to this complete valence shell helium atom is very stable hence does not participate in chemical bonding to form He2 molecule.
