It has only single bonds.So it is saturated
Answer:
Understanding the unit cell of a crystalline solid will help you in determining the empirical formula of the ionic solid compound because they both represent the smallest portion of the whole crystalline solid proportion.
Explanation:
A unit cell is the smallest portion of a crystal lattice, that can show the 3 dimensional pattern of the whole crystal.A formula unit is the lowest whole number ratio of ions in a an ionic compound.By considering the smallest repeating units/ unit cell, you can describe the structure of a crystalline solid.Knowing this can help in determining the empirical formula of the ionic solid compound.
