Explanation / Answer

Now we look at the electron configuration of ions. Give the abbreviated electron configuration for each Be: Sn Be Sn2 Sn' As: Ti: As: Ass K: Zn: Zn Ca Mg' Cl:: Now go back and consider the atoms and ions that are in the same box (this is for the last set only). Place a star by the atom or ion that you think has the largest radius of those options. On a separate sheet of paper do the following First write the complete electron configuration for an atom of Nickel. Then draw the orbital diagram that matches this electron configuration. Then circle 8 electrons of your choice and give the 4 quantum number for each. 72 Electron Configuration
