Face Centered Cubic (FCC) crystal structure has 4 atoms contained per unit cell. The relationship of of radius (R) to the lattice parameter (a) is 4R = a(sqrt(2)). In terms of lattice parameter (a)it is equal to, a = 2R(sqrt(2)).

1/8 for each corner x 8 corners = 1
1/2 for each face x 6 faces = 3
4 total

Why do minerals that have the non-silicate crystalline structure called closest packing have high density?
Minerals with closest packing have high density because their atoms are arranged in a way that minimizes empty space between them. This close arrangement of atoms allows for more atoms to be packed into a given volume, resulting in higher density. Closest packing is a highly efficient crystalline structure that maximizes atomic packing, leading to increased density.
The number and arrangement of electrons in the outer energy level determains the atoms what?
The number and arrangement of electrons in atoms of an element determine the chemical properties of the element.
What is shown by the structural formula of a polyatomic ion?
An arrangement of bonded atoms.
What do molecular formulas and structural formulas have in common?
Molecular formulas contain no information about the arrangement of atoms. Because of this, one molecular formula can describe a number of different chemical structures. A structural formula is used to indicate not only the number of atoms, but also their arrangement in space.
What arrangement of atoms in a repeating pattern in a mineral causes the formation of?
The arrangement of atoms in a mineral sample can cause the formation of crystals.
What are arrangement of atoms by increasing atomic number?
The arrangement of atoms by increasing atomic number are shown in the periodic table.This can be seen from starting at H (Hydrogen) which has the smallest number of atoms and continues on from left to right.
What is the entropy of a solid based on?
The arrangement of the atoms

Atomic packing factor for Bcc?
atomic packing factor (APF) or packing fraction is the fraction of volume in a crystal structure that is occupied by atoms. It is dimensionless and always less than unity. For practical purposes, the APF of a crystal structure is determined by assuming that atoms are rigid spheres. For one-component crystals (those that contain only one type of atom), the APF is represented mathematically by where Natoms is the number of atoms in the crystal, Vatom is the volume of an atom, and Vcrystalis the volume occupied by the crystal. It can be proven mathematically that for one-component structures, the most dense arrangement of atoms has an APF of about 0.74. In reality, this number can be higher due to specific intermolecular factors. For multiple-component structures, the APF can exceed 0.74.
What is shown by the structural formula of a polyatomic ion?
An arrangement of bonded atoms.
Why is it that a diamond is dense?
The atoms in a diamond crystal are in an arrangement called "cubic closest packing". As you might guess from the name, this packs the maximum amount of atoms in the minimum possible space, so diamonds are more dense than, say, graphite, which doesn't pack its atoms as closely together.
The cubic shape of a mineral crystal is most likely the result of that crystal's?
internal arrangement of atoms
What is a chemical formula that shows the numbers and kinds of atoms in a molecule but is not the arrangement of the atoms?
A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.
What is the outward expression of the internal arrangement of atoms is?
Crystal shape is the outward expression of the internal arrangement of atoms, held together in a specific geometrical arrangement.

What is packing factor?
Packing factor is a dimensionless ratio that describes the amount of volume that a substance takes up in a particular volume. For example, if you have a box and you fill it with balls, the volume of the box is taken up by the balls and by the space in between the balls. The packing factor would be (volume of the balls)/(volume of the box). Packing factor is, among other things, relevant to the arrangement of atoms in different crystallographic structures.
