Question

Potential energy of electron present in he+

Answer 1

Potential energy of an electron in the first Bohr orbit of hydrogen atom=2*(-13.6) eV= -27.2 eV. Kinetic and potential energy of atoms result from the motion of electrons. ... In this system of units unit of energy is 27.2 eV. So, potential energy of hydrogen atom in ground state is 1 a.u.

Answer 2

The second element in the periodic table provides our first example of a quantum-mechanical problem which cannot be solved exactly. Nevertheless, as we will show, approximation methods applied to helium can give accurate solutions in perfect agreement with experimental results. In this sense, it can be concluded that quantum mechanics is correct for atoms more complicated than hydrogen. By contrast, the Bohr theory failed miserably in attemps to apply it beyond the hydrogen atom
