Delocalization of electron in hydrogen atom

[sharma_satdev]

if delocalization of electron in hydrogen atom means that it is spread out upto infinity it means that infinite time is required for the electron to be localized when hydrogen atom is ionized.Is it so?

No, it doesn't. A electron doesn't "move" from one place in the atom to another. The instant anything is done to "identify" the electron's postion it "appears" in a position.
