Step 1
Which statement about the ‘ball and stick’ model is correct?
Answer
The correct statement about the ‘ball and stick’ model is:
B - It shows the arrangement of the ions.
The ‘ball and stick’ model visually represents the three-dimensional arrangement of ions within a crystal lattice. The spheres (balls) symbolize the ions, while the sticks connect them, indicating the relative positions of these ions in the structure. This model effectively illustrates how ions are arranged in a systematic manner, although it doesn’t explicitly show the forces, charges, or sizes of the ions.
