The nucleus of a particular atom as a diameter of 11.5 x10-15 m for an electron to be confined within this region, the de broglie wavelength for the electron would have to have to be smaller than this diameter. assuming that the de broglie wavelength was equal to the nucleus diameter, what would be the kinetic energy of the electron in kj/mol? reminder: to specify large values (e. g. a billion) use scientific notation like so: 1e9 note: required precision is 296. 10,409,100.000 question 2 3 pts now let's consider that an electron is confined within this diameter of an entire atom rather than the nucleus. assuming that the de broglie wavelength of the electron was equal to your atomic diameter, 0.31 nm, what would be the kinetic energy of the electron in kj/mol? for a sense of scale, consider that the carbon atoms have a diameter of 0.182 nm and the energy needed to extract an electron from such an atom (the lonization energy) is 11.3 electron volts (ev) or 1090 kj/mol. for comparison, the ionization energy of the smaller hydrogen atom is 13.6 ev or 1312 kj/mol. these energies should be comparable (i. e. a similar order-of-magnitude) to the energy holding the electron within the atom, which should in turn be comparable (and a bit larger) than the kinetic energy associated with electron confinement. reminder: to specify large values (e. g. a billion) use scientific notation like so: 1e9 note: required precision is 1%
