What else can I help you with?
In a solid AB having NaCl structure. A atoms occupy the corners of cubic unit cell if all the face centered atoms along one of the axes are removed then the resultent staichiometry of thesolid is?
Removing all the face-centered atoms along one of the axes in a NaCl crystal removes 1/4 of the original atoms, leaving behind only the atoms at the corners. Since each corner atom is shared between 8 unit cells, the resultant stoichiometry is A:8B.
What is the arrangement of tetrahedral sites within a body-centered cubic (bcc) crystal structure?
In a body-centered cubic (bcc) crystal structure, the arrangement of tetrahedral sites is such that each atom at the center of the cube is surrounded by four tetrahedral sites located at the corners of the cube.
What is the structure of pure gold?
Pure gold typically has a face-centered cubic structure, where each atom is surrounded by 12 nearest neighbors at the corners of a cube and 6 in the faces of the cube. This structure allows gold to be easily reshaped and malleable.
What is the structures of AB2 type ionic crystal?
AB2 type ionic crystal has a structure where cations of A occupy the corners of the unit cell and cations of B occupy the face-centered positions. An example of this structure is fluorite (CaF2) where calcium ions occupy the corners and fluorine ions occupy the face-centered positions.
Why do CsCl and NaCl have different structures?
CsCl (cesium chloride) has a simple cubic structure because the larger Cs+ ions occupy the corners of the cubic unit cell, while the smaller Cl- ions occupy the center of the cell. NaCl (sodium chloride) has a face-centered cubic structure because the Na+ ions occupy the face centers, and the Cl- ions occupy the corners of the unit cell.

What type of holes are therein body centered cubic?
There are no holes in the body-centered cubic (BCC) structure, as it consists of atoms positioned at the corners and one atom at the center of the cube.
What is the arrangement of tetrahedral sites within a body-centered cubic (bcc) crystal structure?
In a body-centered cubic (bcc) crystal structure, the arrangement of tetrahedral sites is such that each atom at the center of the cube is surrounded by four tetrahedral sites located at the corners of the cube.
What is the crystal structure of tungsten?
Tungsten has a body-centered cubic (BCC) crystal structure at room temperature and pressure. In this structure, each tungsten atom is located at the center of a cube, with eight neighboring atoms at the corners.

Pure gold typically has a face-centered cubic structure, where each atom is surrounded by 12 nearest neighbors at the corners of a cube and 6 in the faces of the cube. This structure allows gold to be easily reshaped and malleable.

How are the atoms of aluminum arranged?
Aluminum atoms are arranged in a closely packed metallic structure known as a face-centered cubic (fcc) arrangement. In this structure, each aluminum atom is surrounded by twelve other aluminum atoms at the corners and face centers of the cube.
What is Body Centered Cubic?
Body centered is another cubic unit cell.This unit cell has atoms at the eight corners of a cube and one atom in the center. Once again, the corner atoms are bisected by three orthogonal the planes leaving one-eighth of each atom inside. The central atom is also inside, so this unit cell contains two atoms. Nickel is an example of a substance that has a body centered cubic crystal structure.
In a face-centered cubic structure every atom has twelve neighbors. Which arrangement of balls serves as the best model for this structure?
In a face-centered cubic (FCC) structure, the best model for this arrangement is to represent the atoms as spheres arranged at the corners and the centers of each face of the cube. Each corner atom is shared by eight adjacent cubes, while each face-centered atom is shared by two cubes. This arrangement allows each atom to have twelve equidistant neighboring atoms, corresponding to the FCC's coordination number. The close packing of these spheres maximizes space efficiency and stability in the structure.
Why do CsCl and NaCl have different structures?
CsCl (cesium chloride) has a simple cubic structure because the larger Cs+ ions occupy the corners of the cubic unit cell, while the smaller Cl- ions occupy the center of the cell. NaCl (sodium chloride) has a face-centered cubic structure because the Na+ ions occupy the face centers, and the Cl- ions occupy the corners of the unit cell.
What is a face centered cubic crystal?
A face-centered cubic unit cell is a cube. All sides are the same length and all face perpendicular to each other, with an atom at each corner and an atom in the middle of each face of the cell.
What are examples of a face centered cube?
Examples of face centered cube crystal structure (fcc or ccp) are: Copper, Silver, Gold, Nickel, Aluminum, Helium, Neon, Sulfur, Argon, Calcium, Germanium, Krypton, Strontium, Rhodium, Palladium, Xenon, Ytterbium, Platinum, Iridium, and Lead. http://periodictable.com/Properties/A/CrystalStructure.html
