Crystal Structures
This is the coordination number for a Body-Centered-Cubic (BCC) crystal structure.
What is eight?
This type of defect occurs when a local cation moves to an interstitial site
What is a Frenkel defect?
This constant, represented by "g" equals 9.81 m/s^2.
What is gravity? (at earth's surface)
This subatomic particle, found in the nucleus of an atom, has no electric charge and a mass slightly greater than that of a proton.
What is a neutron?
This material is commonly used in electrical wires due to its excellent conductivity.
What is copper?
This is the number of atoms in the unit cell of a Face-Centered-Cubic (FCC) crystal structure.
What is four?
This defect occurs when both a cation and an anion leave their initial sites, creating two vacancies.
What is a Schottky defect?
This constant, represented by "NA," equals 6.022 × 10²³ mol⁻¹.
What is Avogadro's number?
This type of bond involves the sharing of electrons between atoms.
What is a covalent bond?
This type of steel contains a high amount of chromium, making it resistant to corrosion.
What is stainless steel?
These are the three letters used to designate different axes when describing Miller Indices.
What are H, K, and L?
In a screw dislocation, the Burgers vector is in this orientation relative to the dislocation direction.
What is parallel?
This constant, represented by the letter "R," equals 8.314 J·mol⁻¹·K⁻¹
What is the ideal gas constant?
This law states that the strain in a material is directly proportional to the applied stress, up to the elastic limit.
What is Hooke's Law?
This lightweight metal is often used in the aerospace industry due to its high strength-to-weight ratio.
What is titanium?
When converting from a three-index system to a four-index system, you are converting from Miller Indices to this.
What are Miller-Bravais Indices?
In an edge dislocation, the Burgers vector is in this orientation relative to the dislocation direction.

This constant represented by "c," equals 3x10^8 m/s.
What is the speed of light? (in a vacuum)
This is the measure of a material's resistance to deformation.
What is Young's modulus?
This polymer is known for its exceptional toughness and impact resistance, and is often used in the manufacture of bulletproof glass.
What is polycarbonate?
This is the coordination number for a Face-Centered-Cubic (FCC) crystal structure.
