Yes so during ionization the outermost, least bound electrons will be removed first, and so by calculating wavelength required to remove the last electron we have a sufficient energy to completely ionize.

Ah yes, I think I understand now. So just a matter of calculating the energy required to remove an electron closest to the nucleus, which is in the ground state. Thank you for your help.

1. What is the maximum wavelength of light required to fully ionised Uranium to U92+, i.e. strip it of all electrons and leaving a bare nucleus? For simplicity, only consider direct ionisation and neglect non-linear effects. Attempt at solution Ok, so the electron structure of the...

It's ok, think I have solved it. Using the diffusion and convection equation and setting U=0.

1. For a stationary plasma of electrical conductivity 1.00 x108 Ω-1 m-1 estimate the time taken for a magnetic field to permeate a spherical volume of 3.0 m radius. I have been looking at the question for some time now and I am struggling with where to begin. Any help would be much appreciated.
