How To write an electron configuration: Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. In another words, atoms are built from the ground upwards.
Explain why electrons would be needed to convert oxygen into oxide ion. Explain how, when the oxide turns back into oxygen, a current can flow from the platinum electrode on one side of the material, through a circuit and bac to the other platinum electrode.
Naming Ions. assign problems 4, 8–15. Essential Understanding Ions are named by determining their charges and applying certain rules. Reading Strategy. Concept Map A concept map helps you organize concepts, using visual relationships and linking words. Mapping out these connections helps you think about how information fits together.
