Only electrons can move in or out of atoms.

When an object is charged, it is only the .............. (protons/electrons) that can move in or out of an atom.

The angular momentum of an electron in a given stationary state can be expressed as m_(e)vr=n(h)/(2pi) . Based on this expression an electron can move only in those orbits for which its angular momentum is

An electron is moving in 3rd orbit of Hydrogen atom . The frequency of moving electron is

An electron is moving in an orbit of a hydrogen atom from which there can be a maximum of six transition. An which there can be a maximum of three transition. Find ratio of the velocities of the electron in these two orbits.

Hydrogen atom: The electronic ground state of hydrogen atom contains one electron in the first orbit. If sufficient energy is provided, this electron can be promoted to higher energy levels. The electronic energy of a hydrogen-like species (any atom//ions with nuclear charge Z and one electron) can be given as E_(n)=-(R_(H)Z^(2))/(n^(2)) where R_(H)= "Rydberg constant," n= "principal quantum number" The energy in Joule of an electron in the second orbit of H- atom is:
