← In the Bohr model, compare the electron of a He⁺ ion (Z = 2) in the orbit n = 4 with the electron of a Li²⁺ ion (Z = 3) in the orbit n = 6. For orbit n of a one-electron species, the radius goes as n²/Z and the energy as -Z²/n². Which of the following are the same for the two electrons?A krypton atom (Z = 36) is in its ground state, 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶. Each of its electrons has four quantum numbers n, l, ml and ms. Which of the following statements about the electrons of this atom are correct? →
