Nucleate boiling is a condition in which bubbles of steam nucleate at points on a metal surface and minute concentrations of solids develop at the interface of the bubbles and water.

No, @Adarsh you are wrong. In film boiling, bubbles form more rapidly so that they coalesce into a vapour film that insulate the heating surface & preventing the inflow of fresh liquid. Film boiling is not generally desired in heat transfer equipment.
