Who postulated the existence of temporary dipole attraction among nonpolar molecules?
Fritz London was the scientist who postulated the existence of temporary dipole attraction among nonpolar molecules, an idea known as London dispersion forces. These forces are due to the fluctuations of electron distribution in molecules, resulting in temporary dipoles that attract one another.
Which scientist first postulated the existence of ions?
Michael Faraday is credited with first postulating the existence of ions in 1834. He observed that chemical compounds decompose into electrically charged particles when dissolved in water and demonstrated that electric current could flow through a solution of ions.
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.
What information does the first quantum number of an electron give?
The energy level the electron is in
What subatomic particle was first discovered?
This particle was the electron in 1897 (J.J. Thomson).

Austrian physicist who postulated the existence of the neutrino?
Wolfgang Pauli
What is the achievements of the Greece philosopher Democritus?
Democritus and his mentor Leucippus postulated the existence of the atom.

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.
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.
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.
How were neutrino discovered?
Neutrinos were first postulated by Wolfgang Pauli in 1930 to explain the missing energy and momentum in beta decay. They were experimentally confirmed by Clyde Cowan and Frederick Reines in 1956 through the detection of electron antineutrinos produced in a nuclear reactor.
Who first postulated that continents drift around over the Earth's surface?
Afred Wegener
Describe experimental basis for existence of electrons in an atom?
J.J. Thompson proved the electron's existence through the cathode ray experiment.
