A π (pi) bond is the result of the
overlap of two s orbitals
overlap of an s orbital and a p orbital
overlap of two p orbitals along their axes
sidewise overlap of two parallel p orbitals
sidewise overlap of two s orbitals
When comparing Be2 and H2:
I.Be2 is more stable because it contains both bonding and antibonding valence electrons.
II.H2 has a higher bond order than Be2.
III.H2 is more stable because it only contains σ1s electrons.
IV.H2 is more stable because it is diamagnetic, whereas Be2 is paramagnetic.
I, II
