Question1

Assume that we have the Hydrogen atom and the electron in the Hydrogen atom is in the n = 4 state. What should be the least kinetic energy in electron volts of the incident electron that can ionize the Hydrogen atom?

Question2

I am having trouble accessing labs 3 and 4 for my physics 102 course at Drexel University. In its place of being directed to a .pdf like the first two labs on this site, I am instead directed to a school run website in which the labs are not available. Can you help me increase access to pages for labs 3 & 4 for this class?
