Aug 23, 2021 · The term "closest packed structures" refers to the most tightly packed or space-efficient composition of crystal structures (lattices). Imagine an atom in a crystal lattice as a sphere. While cubes may easily be stacked to fill up all empty space, unfilled space will always exist in the packing of spheres.
Aug 14, 2020 · The definition and significance of the unit cell. Sketch the three Bravais lattices of the cubic system, and calculate the number of atoms contained in each of these unit cells. Show how alternative ways of stacking three close-packed layers can lead to the hexagonal or cubic close packed structures.
An empty body diagram, also known as a free-body diagram, is a diagram that represents the forces acting on an object. It is a simplified representation that shows only the forces and their magnitudes and directions, without any other details.
Oct 18, 2024 · Representation of orbitals (the dot represents the nucleus of the atom) showing spherical s orbitals (a), p orbitals containing ‘lobes’ along the x, y and z axis. Note that the shape of the d orbitals is not required. An overview of the shells, subshells and orbitals in an atom.
Learn about and revise small molecules with this BBC Bitesize GCSE Chemistry (AQA) study guide.
We will look at the ionic structures in the next section, and here focus on the generic unit cell and it's application to metallic structures. There are 7 types of unit cells (figure 12.1.a), defined by edge lengths (a,b,c) respectively along the x,y,z axis and angles α, β, and γ.

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions.
