The total energy of an electron in the first excited state of the hydrogen atom isabout –3.4 eV.What is the kinetic energy of the electron in this state?What is the potential energy of the electron in this state?

A hydrogen atom is in an excited state with n = 2. Using the Bohr model of hydrogen, find the following.the radius of the electron orbit (in nm).Answer for part 1the angular momentum of the electron - use SI unitsAnswer for part 2the kinetic energy of the electron (in eV).Answer for part 3the potential energy of the electron (in eV).  Note that this may be a negative number.Answer for part 4the total energy of the electron (in eV). Note that this may be a negative number.

The ionization energy of a hydrogen-like atom is 14.4 eV. The amount of energy released whenelectron jumps from the fourth orbit to the first orbit in this atom is (in eV)

If the binding energy of an electron in a hydrogen atom is 13.6 eV, then the energy required to remove the electron from the first excited state of Li++ isA.30.6 eVB.13.6 eVC.3.4 eVD.122.4 eV

An electron is in an excited state in a hydrogen like atom. It has a total energy of −3.4 eV. The kinetic energy of the electron is E and its de Broglie wavelength is λ

The excitation energy of an electron from second orbit to third orbit of a hydrogen-like atomor ion with +Ze nuclear charge is 47.2eV . If the energy of H-atom in the lowest energy state is -13.6 eV , then the value of Z is
