How do you find the energy of the first excited state?
For hydrogen-like atoms, i.e. H , He+ , Li2+ , etc., the energy levels are given by:
- En=−Z2⋅13.61 eVn2. where Z is the atomic number and n is the quantum level.
- E2=−22⋅13.61 eV22. =−13.61 eV.
- E1=−22⋅13.61 eV12. =−54.44 eV.
What is the energy of the second excited state of hydrogen?
The total energy of an electron in second excited state of hydrogen atom is -1.51eV.
What is the kinetic energy of an electron in the second excited state of He+?
The correct option is (4) -6.04.
What is the formula of excitation energy?
The excitation energy of an energy state is the difference between the energy of the excited state and that of the ground state. For example, for the hydrogen atom, the ground state energy(energy of the first orbit) is E1 = -13.6 eV and energy of the second orbit is E2 = -3.4 eV.
How do you calculate the energy of a state?
1 Answer
- E=−13.6n2 where the energy is in electron volts.
- n is the principle quantum number.
- So for an electron in n=1 :
- E=−13.6eV.
- To convert to joules you can x this by 1.6×10−19.

For which atom or iron the energy level of the second excited state is 13.6 eV?
the ground state energy of hydrogen atom is – 13.6 eV .
For which atom or ion the energy level of the second excited state is 13.6 eV a h b He (+) C Li 2 +) d Li?
What is meant by second excited state?
Energy levels higher than ground energy state in an atom is called as excited energy state/ level. Energy of electron in second excited state means : Z=1, n=3.
What is the potential energy of the second orbit of H E+?
Potential Energy is -27.2 eV in second orbit of H e+ then calculate double of total energy in the first excited state of hydrogen atom – 6.8 eV. Total energy is one half the potential energy. Second orbit of H e+ has a total energy of −27.2 eV. Hence, its total energy will be 2−27.2
What is the potential energy of a hydrogen atom in H+?
Potential energy is -27.2 eV in the second orbit of H e+, then calculate double of total energy in the first excited state of hydrogen atom.
What is the energy of an electron in the first excited state?
The total energy of an electron in the first excited state of the hydrogen atom is about -3.4 eV.
What is the potential energy of the electron?
(b) Using V = 2T, potential energy of the electron is = 6.8 eV. (c) If the zero of potential energy is chosen differently, kinetic energy does not change. Its value is + 3.4 eV independent of the choice of the zero of potential energy.
