Experimental data shows that the nucleus of an atom underline ( ) has no charge is mostly empty space contains most of the mass of the atoms contains mostly negative charge

Experimental data shows that the nucleus of an atom:<br /><br />- is mostly empty space (this is true for the entire atom, not specifically the nucleus)<br />- contains most of the mass of the atoms (correct)<br />- contains mostly negative charge (incorrect; it contains positive charge due to protons)<br /><br />Therefore, the correct statement is:<br /><br />**contains most of the mass of the atoms**
