No, they are completely different. An atomic nucleus is the core of an atom (protons and neutrons). A crystal nucleus is a cluster of atoms/molecules that seeds the growth of a macroscopic crystal.
Its primary use is technical. It can be used metaphorically in advanced writing (e.g., history, literary criticism) to describe the origin of a complex movement or idea, but this is rare.
The plural is 'crystal nuclei' (/ˈnuː.kli.aɪ/ in US, /ˈnjuː.kli.aɪ/ in UK).
'Nucleation' is the overall process of forming a new thermodynamic phase (like a crystal from a liquid). A 'crystal nucleus' is the specific, stable cluster of the new phase that forms during that process and is capable of further growth.
The initial microscopic cluster of atoms, ions, or molecules from which a crystal grows.
Crystal nucleus is usually technical/scientific (chiefly materials science, chemistry, geology, physics); occasionally used in metaphorical academic writing. in register.
