FREE Expert Solution

We have to determine how many repulsive interactions are shown for ion 5 in the given diagram.


We will start by the fact that opposite charges attract each other, and same charges repel each other.

In the given diagram, the sodium ions (Na+) are shown by purple spheres and the chloride ions (Cl-) are shown by green spheres.

Problem Details
A portion of a two-dimensional "slab" of NaCl(s) is shown here in which the ions are numbered.

Atoms 1, 3, 5, 7 and 9 are all one element; 2, 4, 6, and 8 are all the same different element.

Consider ion 5. How many repulsive interactions are shown for it?
