Which interstial site is larger octahedral or tetrahedral?
Octahedral sites are larger than tetrahedral sites because octahedral sites have more space available for an atom or ion to occupy. This is because octahedral sites are formed by six atoms or ions arranged in an octahedral shape, while tetrahedral sites are formed by four atoms or ions arranged in a tetrahedral shape.
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 fluorite?
Fluorite has a cubic crystal structure, meaning that its crystal lattice is composed of repeating cubes. The atoms or ions are arranged in a face-centered cubic arrangement, with fluoride ions occupying the lattice points and calcium ions occupying the octahedral sites within the structure.
Why carbon is more in FCC iron when compared to BC iron even though FCC iron structure has less void space?
In FCC iron, carbon atoms can occupy octahedral sites, contributing to solid solubility. BC iron has fewer octahedral sites available for carbon, limiting solid solubility. Therefore, more carbon can be accommodated in FCC iron despite having a smaller void space.
What is mean by Octahedral sites?
An octahedral position for an (interstitial) atom is the space in the interstices between 6 regular atoms that form an octahedra. Four regular atoms are positioned in a plane, the other two are in a symmetrical position just above or below. All spheres can be considered to be hard and touching each other. The six spheres define a regular octahedra, in its interior there is a defined space for an interstitial atom, bordered by six spheres.
What is Fe AlO2?
Fe(AlO2)2 iron(II) aluminate is better written as FeAl2O4, and is better described as a mixed oxide with close packed oxide ions and Fe2+ and Al3+ occupying tetrahedral and octahedral sites, a spinel structure.
What is the number of spheres in hexagonal close-packed crystal structure?
The hexagonal structure of alternating layers is shifted so its atoms are aligned to the gaps of the preceding layer. The atoms from one layer nest themselves in the empty space between the atoms of the adjacent layer just like in the fcc structure. However, instead of being a cubic structure, the pattern is hexagonal.The hcp structure has three layers of atoms. In each the top and bottom layer, there are six atoms that arrange themselves in the shape of a hexagon and a seventh atom that sits in the middle of the hexagon. The middle layer has three atoms nestle in the triangular "grooves" of the top and bottom plane. Note that there are six of these "grooves" surrounding each atom in the hexagonal plane, but only three of them can be filled by atoms.SAMPLE:· Nickel Arsenide Structure s based on a distorted hcp array of Arsenide anions. By contrast with the wurtzite structure, however, which is also of formula AB, the cations now occupy all the octahedral sites rather than half the tetrahedral holes. There is one octahedral hole for each hcp lattice site, and so the AB stoichiometry is preserved.· Titanium Oxide, TiO2. he anions occupy the hcp lattice, and the cations occupy half of the octahedral holes.LutetiumThalliumTerbium
What is an atomic crystal?
A crystallike structure of atoms that occupy sites in an optical lattice.

What is a tertiary protein structure exemplified by?
A tertiary protein structure is the three-dimensional arrangement of a polypeptide chain. An example of a tertiary protein structure is the globular shape of enzymes like catalase or lysozyme. This structure is crucial for the protein's function as it determines the active sites and binding sites.
