which model shows the stable ionic compound that forms rubies?
Answer
Explanation:
Step1: Identify rubies composition
Rubies are mainly composed of aluminum oxide ($Al_2O_3$), an ionic compound. Aluminum ($Al$) forms $Al^{3 + }$ ions and oxygen ($O$) forms $O^{2 - }$ ions. To form a neutral compound, we need 2 aluminum ions and 3 oxygen ions.
Step2: Analyze models
We need to find a model with a ratio of 2 cations (representing $Al^{3+}$) and 3 anions (representing $O^{2 - }$). Without seeing the actual colors - coded meaning of the spheres in the models, we assume the model with the correct ratio of the two types of spheres is the answer.
Answer:
We cannot determine the answer without knowing which color of spheres represents which ion. If we assume red spheres are oxygen - containing anions and light - colored spheres are cations, we need to find the model with 3 red spheres and 2 light - colored spheres.
