Question 1

The nucleus of a particular atom as a diameter of 7.1 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 2%.

Sanity check: The expected answers should be between: 6e11 and 8e13. The energy required to

keep an electron confined to a nucleus is crazy large, this is why electrons don't reside in the

nucleus to be near the protons.
