An element cannot be separated into simpler substances by chemical means.
A compound, such as water (H2O), cannot be physically separated into its component elements (hydrogen and oxygen) but can be chemically separated through a chemical reaction, such as electrolysis, which breaks the bonds between the elements.
Nucleus and nucleolus cannot be separated by centrifugation because both are dense structures that pellet together during this process. They have similar densities and thus cannot be effectively separated based on their mass alone.
