Ahydrogen-like ion is an ion containing only one electron. the energies of the electron in a hydrogen-like ion are given by en = −(2.18 × 10−18j) z2 (1/n2) where n is the principal quantum number and z is the atomic number of the element. calculate the ionization energy (in kj/mol) of the he+ ion.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
