N3- Zn2+ Aluminum, Al Aluminum chloride, AlCl3 Chlorine, Cl2 Acetone, C3H6O Carbon monoxide, CO Cobalt, Co atomic element ionic compound molecular element molecular compound molecular compound atomic element Ionic Compounds Predicting Ionic Charge with Periodic Table (memorize these) Ag+ Compounds must be neutral (charge=0), therefore the numbers of cations and anions in a compound must balance to get 0 charge. Classify each of the following as: Electrons + Neutrons + Protons Atoms with examples: nitrate- NO3- , sulfate- SO42- ,p...
