The nucleus of an atom is on the order of 10-15 m in diameter. For an electron to be confined to a nucleus, its de Broglie wavelength would have to be on this order of magnitude or smaller.
(a) What would be the kinetic energy of an electron confined to this region?
------------------ eV
(b) Make also an order-of-magnitude estimate of the electric potential energy of a system of an electron inside an atomic nucleus. 10
---------------- eV
