The α -particle scattering experiment of Rutherford concluded that:
(1) The nucleus is made up of protons and neutrons
(2) The number of electrons is exactly equal to number of protons in atom
(3) The positive charge of the atom is concentrated in a very small space
(4)Electrons occupy discrete energy levels
Ans: The positive charge of the atom is concentrated in a very small space
EDTA charge is 4.and it is react with many compound to form other compounds
