1. The alpha particle scattering experiment was carried out by   E. Rutherford   E. Goldstein   J. J. Thomson   J. Chadwick   Hint Half-n-half Clue   2. As a result of Rutherford's scattering experiment, it was concluded that   the center of the atom has a negative charge.   the center of the atom is empty.   atomic mass is spread over the whole atom.   most of the atom is empty.   Half-n-half Clue   3. The smallest particle of an element which can take part in chemical reactions and may or may not exist independently is the   neutron   compound   atom   nucleus   Half-n-half Clue   4.
