No...

In fact, gases have densities THOUSANDS of times lower than liquids and solids. Gases generally have little intermolecular forces going on, which is why they are freely-moving particles in the first place.

  • The density of #"H"_2(g)# is about #"0.08988 g/dm"^3# at STP.
  • The density for water at STP is #"999.8425 g/dm"^3#.
  • The density of gold, one of the softest metals, at room temperature and pressure, is #"19320 g/dm"^3#.
