How Many Atoms to Draw in an FCC Lattice Problem?

In summary, the conversation discusses the Miller index and the number of atoms at the corner and centre of a face. The participants also mention a website with more information on aluminum's crystal structure and suggest drawing at least 10 atoms for accuracy.

Isn't (100) the YZ plane?
See images at https://en.m.wikipedia.org/wiki/Miller_index.
Yes. So isn't there 4 atoms at the corner and an atom in the centre of a face?

It would by all right, but you should draw at least 10 atoms.

1. What is a FCC lattice?

A FCC (face-centered cubic) lattice is a type of crystal structure in which the atoms are arranged in a cubic pattern with atoms located at each corner and in the center of each face of the cube.

2. How is a FCC lattice different from other crystal structures?

A FCC lattice is unique because it has the highest packing efficiency among all crystal structures, meaning that it can accommodate the most number of atoms in a given volume.

3. What are the properties of a FCC lattice?

Some properties of a FCC lattice include high strength and ductility, good thermal and electrical conductivity, and resistance to corrosion.

4. How is a FCC lattice used in real-world applications?

FCC lattices are commonly used in the production of metals, such as aluminum, copper, and gold, which are used in various industries including construction, electronics, and jewelry making. They are also used in the development of new materials for advanced technologies.

5. Can a FCC lattice be distorted or deformed?

Yes, a FCC lattice can be distorted or deformed under certain conditions, such as high temperatures or external forces. This can result in changes in the lattice structure and properties of the material.
