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

If the kinetic energy of electron in n^( th ) shell of H - atom is K then its potential energy in n^(th ) shell will be

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 ?

r_(n,z)= Radius of nth orbit of a single electron species having atomic number 'z' u_(n,z)= Velocity of electron in nth orbit of a single electron specie having atomic number 'z' E_(n,z) = Magnitude of total energy of electron in nth orbit of a single electron species having atomic number 'z'. K_(n,z)= Magnitude of kinetic energy of electron in nth orbit of a single electron species having atomic number 'z' P_(n,z)= Magnitude of potential energy of electron in nth orbit of a single electron species having atomic number 'z' f_(n,z)= Frequency of electron in nth orbit of a single electron species having atomic number 'z'. T_(n,z)= Time period of electron in nth orbit of a single electron species having atomic number 'z'

Which of the following option(s) is/are independent of both n and Z for H- like species? U_(n) = Potential energy of electron in n^(th) orbit KE_(n) = Kinetic energy of electron in n^(th) orbit l_(n) = Angular momentam of electoron in n^(th) orbit v_(n) = Velcity of electron in n^(th) orbit f_(n) = Frequency of electron in n^(th) orbit T_(n) = Time period of revolution of electron in n^(th) orbit
