What is the kinetic energy of second excited state of helium?

The correct option is (4) -6.04.

What is the energy of electron in second excited state?

5eV and −3eV.

What is the second excited state of hydrogen?

If it jumps to third energy it is in a second excited state and so on. For a hydrogen atom Z=1. When the hydrogen is in a second excited state, the value of n is equal to 3. Therefore, the radius of a hydrogen atom when it is in its second excited state is nine times its radius when it is in its ground state.

What is the energy of an electron in ground state of He+ in eV?

Answer: observed ionization energy of He+ from the ground state is exactly 54.4 eV. In neutral helium with two noninteracting electrons, the ionization energy would also be 54.4 eV and the ground state energy would be –108.8 eV.

How do you find the energy of a second excited state?

For hydrogen-like atoms, i.e. H , He+ , Li2+ , etc., the energy levels are given by:

1. En=−Z2⋅13.61 eVn2. where Z is the atomic number and n is the quantum level.
2. E2=−22⋅13.61 eV22. =−13.61 eV.
3. E1=−22⋅13.61 eV12. =−54.44 eV.

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 kinetic energy of an electron in the ground state of hydrogen?

-13.6 eV
The energy of the electron in the ground state of hydrogen atom is -13.6 eV.

What would be the radius of 2nd excited state in li2+?

Answer: The radius of 2nd excited state in ion is 70.53 pm.

What is the energy of the third excited state of hydrogen?

Given, initially, in a hydrogen atom, the electron is in ground state ∴n=1. Therefore, the energy of the electron in ground state is −13.6eV. Therefore, the energy required to move electrons from ground state to third excited state is 12.75eV.

What is the binding energy of second excited state of He+ ion?

The He+ ion is just like a hydrogen atom with two units of charge in the nucleus. Since the hydrogenic energy levels depend upon the square of the nuclear charge, the energy of the remaining helium electron should be just 4x(-13.6 eV) = -54.4 eV as observed.

What is the ionization energy of He+ ion?

The He+ ion is similar to the hydrogen atom but with two units of charge in the nucleus. The energy of the remaining helium electron should be 4 × (− 13.6 eV)= − 54.4 eV as observed. To remove the second electron, the energy of 54.4eV is required.

What would be the radius of 2nd excited state in Li2+?
