- 20.The energy of an electron in a one electron atom equals (-2.18 x 10-18 J)(Z2/n2) , where Z is the nuclear charge and n is the principal quantum number of the electron. This is not actually correct because it ignores shielding effects. Assuming that an alkali metal can be viewed this way and referring to the outermost electron, calculate the ionization potential in J. of Lithium Report as a positive number. Answer example: 3.451e-18
