" The energy of "n^(" th ")" orbit in an atom in joules is given by "

" Energy of the n^(th) orbit "-

The energy of the elecron in an orbit of hydrogen atom is given by E_(n)=-1311.8/(n^(2))kJ "mol"^(-1) The ionisation energy of hydrogen atom is:

Kinetic energy of electron in n^("th") orbit in H-atom

Time period of revolution of an electron in n^(th) orbit in a hydrogen like atom is given by T = (T_(0)n_(a))/ (Z^(b)) , Z = atomic number

Time period of revolution of an electron in n^(th) orbit in a hydrogen like atom is given by T = (T_(0)n_(a))/ (Z^(b)) , Z = atomic number

" Kinetic energy of electron in "n''" orbit in H-atom "

State Bohr's postulates. Using these postulates, derive an expression for total energy of an electron in the n^("th") orbit of an atom. What does negative of this energy signify ?
