Energy required to strip final electron

In summary, the formula for finding the energy (En) in electron-volts required to remove the remaining electron from a doubly ionized lithium (Li2+) atom is En=-z^2/n^2, where z represents the atomic number. However, this formula may need to be double-checked as it does not seem to work for lithium. Another approach could be to treat the remaining electron like hydrogen and use the formula z (or E1) = -13.6 eV. Further research and clarification may be needed.

Homework Statement



Find the energy in electron-volts required to remove the remaining electron from a doubly ionized lithium (Li2+) atom.

Homework Equations



En=-z^2/n^2

The Attempt at a Solution



I thought z was 3 for lithium, that doesn't work. I thought since there was only one remaining electron you could treat it like Hydrogen and use z (or E1) = -13.6 eV but that's not right either. Clearly the n in the denominator is 1 from above.

I'm lost!

What is the definition of "Energy required to strip final electron"?

The energy required to strip a final electron is the amount of energy needed to remove the outermost electron from an atom or molecule, resulting in the ionization of the atom or molecule.

How is the energy required to strip a final electron calculated?

The energy required to strip a final electron is calculated using the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the light or radiation used in the ionization process.

What factors affect the energy required to strip a final electron?

The energy required to strip a final electron can be affected by the atomic or molecular structure, the strength of the electric field, and the intensity and frequency of the light or radiation used in the ionization process.

Why is the energy required to strip a final electron important in scientific research?

The energy required to strip a final electron is important in scientific research because it can provide valuable information about the electronic structure of atoms and molecules. It is also used in various analytical techniques, such as mass spectrometry, to identify and study chemical compounds.

Can the energy required to strip a final electron be measured experimentally?

Yes, the energy required to strip a final electron can be measured experimentally using techniques such as photoelectron spectroscopy, where the energy of the emitted electrons is measured and used to calculate the ionization energy of the atom or molecule.
