The ratio of energies of first excited state of He+ ion and ground state of H-atom is

What is the ionization energy (in kJ/mol) of the atom in its first excited state?

A hydrogen atom in an excited state can be ionized with less energy than when it is in its ground state. What is n for a hydrogen atom if 0.278 eV of energy can ionize it?

A hydrogen-like atom (atomic number Z) is in a higher excited state of quantum number n. Thisexcited atom can make a transition to the first excited state by successively emitting two photonsof energies 10.20 and 17.00 eV, respectively. Alternatively, the atoms from the same excited statecan make a transition to the second excited state by successively emitting two photons of energies4.25 and 5.95 eV, respectively.a) The value of ‘n’ and ‘Z’ respectively are –b) How much energy will be emitted when an electron in this atom moves from (n + 1) toground state?

The energy of electrons in the ground state of the hydrogen atom can be expressed as:Group of answer choices-2.18 x 10-18 J atom-1-2.18 x 10-18 J mol-1-1312 kJ atom-1-5.45 x 10-19 J atom-1-1 J mol-1

The minimum energy required by a hydrogen atom in ground state to emit radiation in Balmer series is nearly:
