No, it is a physical, not chemical change.
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.
Beryllium's chemical symbol is Be.
