Here we have to explain if is it possible for a salt of formula AB3 to have a face-centered cubic unit cell of anions with cations in all the eight available holes.
Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it becomes a definitely charged cation. If a balanced atom gains one or greater electrons, it becomes a negatively charged anion.
Cations are definitely charged ions. they are formed when a metal loses its electrons. They lose one or multiple electrons and no longer lose any protons. therefore, they own a net fine price. some examples of cations are Calcium (Ca2+), Potassium (okay+), and hydrogen (H+).
There are several things to word about the ions in parent 1. First, each element that forms cations is a metal, besides for one (hydrogen), whilst every detail that bureaucracy anions are a nonmetal.
In a face-centered cubic cell, there are 8 corners and 6 faces.
The face-centered cell has 6 atoms in the faces, thus the total atoms = 6 ½ = 3 atoms. In the face-centered cell, the arrangements of atoms will be corner +face i.e 3 +1 atoms = 4 atoms.
Hence total of 4 atoms are present in the cell, thus the ratio of cation and anion in the fcc lattice must be in a 2:1 ratio and the formula of the salt should be only AB2.
Therefore the formula AB3 is not possible to have a face-centered cubic unit cell of anions with cations in all the eight available holes.
