Answer:

RbI

Explanation:

The formula of a compound can be obtained on the basis of number of anion and cations in the unit cell. Iodide is present at the eight corners of the cubic cell.

So, no. of iodide ion = 1/8×8= 1

rubidium is present at the center

so, no. of rubidium ion = 1×1 =1

Therefore formula of the compound = RbI
