- By now you’ve noticed that the cards represent charged ions. If you want to combine these ions to make a stable material, what does the total charge need to be on the final product? Ionic materials share similar properties when it comes to how they respond to forces, melting/boiling temperatures, how they interact with light, and how they conduct electricity. What are those properties, and what are the electrons doing that cause those observed behaviors?How many grams of N2 are needed to produce 2.17 mol of NH3 when reacted accordinng to this chemical equation? N2(g) +3H2(g)=NH3(g)Choose the corect answer : The forces that are bond between atoms in the molecular solid are described as a) Electrostatic forces b) Covalent forces c) Dipole Dipole forces d) Metallic forces
