We’re being asked to construct the orbital diagrams for Mo3+ and Zr2+. For this problem, we need to do the following:Step 1: Determine the electron configuration of the neutral element.Step 2: Determine the electron configuration of the ion.Step 3: Construct the orbital diagram for the ion.[readmore]For Mo3+:Step 1: Recall that for a neutral element, Atomic number = # of protons = # of electrons. The atomic number of Mo is 42 which means Mo has 42 electrons.Based on the figure, Mo belongs in the d-block in Period 5 so its electron configuration will contain the 4d and 5s subshells. Recall that: • s–subshell can hold a maximum of 2 electrons• p–subshell can hold a maximum of 6 electrons• d–subshell can hold a maximum of 10 electrons• f–subshell can hold a maximum of 14 electronsStarting from 1s, the electron configuration for Mo is:Mo: 1s22s22p63s23p64s23d104p65s24d10Step 2: The +3 charge means 3 e– was removed from Mo. Therefore, we need to remove 3 e– starting from the highest energy level (5s).The electron configuration for Au+ is:Mo: 1s22s22p63s23p64s23d104p64d9Step 3: For the orbital diagram, we simply need to draw each orbital and fill them up with the correct number of electrons. When filling up the orbitals, take note of:• Aufbau Principle: totally fill in the lowest energy orbital first• Hund’s Rule: electron orbitals that are degenerate (same energy orbital) are first half-filled before they are totally filledThe orbital diagram for Mo3+ is:For Zr2+:Step 1: Recall that for a neutral element, Atomic number = # of protons = # of electrons. The atomic number of Zr is 40 which means Zr has 40 electrons.The location of Zr in the periodic table is shown below:Based on the figure, Zr belongs in the d-block in Period 5 so its electron configuration will contain the 4d and 5s subshells. Recall that: • s–subshell can hold a maximum of 2 electrons• p–subshell can hold a maximum of 6 electrons• d–subshell can hold a maximum of 10 electronsStarting from 1s, the electron configuration for Zr is:Zr: 1s22s22p63s23p64s23d104p65s24d2Step 2: The +2 charge means 2 e– were removed from Zr. Therefore, we need to remove 2 e– starting from the highest energy level (5s).The electron configuration for Zr2+ is:Zr: 1s22s22p63s23p64s23d104p64d2Step 3: For the orbital diagram, we simply need to draw each orbital and fill them up with the correct number of electrons. When filling up the orbitals, take note of:• Aufbau Principle: totally fill in the lowest energy orbital first• Hund’s Rule: electron orbitals that are degenerate (same energy orbital) are first half-filled before they are totally filledThe orbital diagram for Zr2+ is:
