Oxygen Ions in Space- the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite has been analyzing the spectra of emission sources within the Milky Way. Amid the satellite's findings are interplanetary clouds containing oxygen atoms that have lost five electrons.
a. State an electron configuration for these highly ionized oxygen atoms.
b. Explain which electrons have been removed from the neutral atoms?
c. Define the ionization energies corresponding to removal of the third, fourth, and fifth electrons are 4581 kJ/mol, 7465 kJ/mol, and 9391 kJ/mol, respectively. Define why removal of each additional electron requires more energy than removal of the previous one.
d. Explain what is the maximum wavelength of radiation that will remove the fifth electron from O4+?
