It doesn't make a lot of sense to talk about an electron's path, because electrons in atoms don't have paths period, whether circular, elliptical, or banana-shaped. They have orbitals, which despite the similarity in sound are not at all the same thing as orbits.
Answer2. Motions are elliptical when the central force exceeds the centrifugal force and the atom, electron or planet is bound by the central force.
no
Work done is always zero, whatever be the shape of the orbit because electron will be in the same energy state after it completes an orbit
I think that it is impossible for a massless body to move an electron from its path. Photons are massless but how they are able to displace an electron having mass.
Its Orbit.Johannes Kepler (Germany), who lived between the time of Copernicus (Poland) and Isaac Newton (England), correctly postulated that all of the sun's planets indeed revolve about the sun in orbits which have the shape of an ellipse, with the sun at one focus of the ellipse. Isaac Newton, in his Principiae Mathematica, further stated, essentially, that any planet orbiting any star, or any moon orbiting any planet, would follow an elliptical path.
