the repeating subunits that are responsible for the shape of a crystal are known as unit cells. heavy nuclei. light electrons. amorphous cells.

the repeating subunits that are responsible for the shape of a crystal are known as unit cells. heavy nuclei. light electrons. amorphous cells.

Answer

Brief Explanations:

In crystallography, unit - cells are the repeating subunits that determine the shape and structure of a crystal. Heavy nuclei, light electrons, and amorphous cells are not relevant in this context. Amorphous substances do not have a regular, repeating structure like crystals.

Answer:

unit cells.
