Which scientist first postulated the existence of ions?
J J Thomas
Who postulated the existence of temporary dipole attraction among nonpolar molecules?
dalton
Who proved the existence of the electron?
Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. But many scientists contributed to the discovery of the electron.

Who postulated the existence of the neutrino?
Walter Baade and Fritz Zwicky proposed the existence of the neutron star in 1934. Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula" in 1965, which turned out to be the Crab Nebula neutron star.
Who proposed the existence of electron?
‎J. J. Thomson discovered the electron in experiments done in 1897.
Was niels bohr the first to come up with the atom?
No. Ancient Greek philosophers postulated the existence of atoms.In 1803, John Dalton proposed an atom to explain chemical reactions that had been observed by scientists since the 1800's.
Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
What was the name of the scientist that first postulated the theory of atomic structure?
John Dalton.. :))
Describe experimental basis for existence of electrons in an atom?
J.J. Thompson proved the electron's existence through the cathode ray experiment.
