Sub atomic particles of atoms are

The kinetic energy of a sub-atomic particle is 5.65xx10^(-25)J . Calculate the frequency of the particle wave.

J. chadwick discovered a sub atomic particle which has no charge but has mass nearly equal to that of a proton.Name the particle and give its location in an atom.

Discovery Of Neutrons And Other Particles Of Atom

An atom consists of the sub-atomic particles protons, electrons, and ___________

Statement -1 : Large angle scattering of alpha particles led to the discovery of atomic nucleus. Statement -2 : Entire positive charge of atom is concentrated in the central core.
