3.5.6.1 Solution pipee-a
Question:
Plug the mass of an electron, 9.109 38 10 kg, and the rough size of an hydrogen atom, call it 2 10 m, into the expression for the ground state kinetic energy and see how big it is. Note that 1.054 57 10 J s. Express in units of eV, where one eV equals 1.602 18 10 J.
Answer:
or 9.4 eV. The true value is about 4.5 eV. That is in the ball park.
