Answer
Explanation:
Step1: Identify elements by color
Purple is Li or K, green is F, red is Br.
Step2: Match formulas to models
- First model has purple and green balls, so it is LiF as Li is smaller than K and more likely to be in a structure with F in this pattern.
- Second model has purple and red balls, so it is LiBr.
- Third model has larger purple balls (K) and green balls, so it is KF.
Answer:
First model: LiF Second model: LiBr Third model: KF
