Suppose the velocity of an electron in an atom is known to an accuracy of 2.0×103 m/s (reasonably accurate compared with orbital velocities). What is the electron’s minimum uncertainty in position, and how does this comparewith the approximate 0.1-nm size of the atom?
If the electron in a hydrogen atom obeyed classical mechanics instead of quantum mechanics, would it emit a continuous spectrum or a line spectrum? Explain.
If someone wanted to build a scale model of the atom witha nucleus 1.00 m in diameter, how far away would the nearestelectron need to be?
