What is a crystal lattice also known as Mcq?
Crystal lattice is a regular arrangement of the constituent atoms or ions or molecules in three-dimensional space.
A crystal lattice also called a space lattice or simply, a lattice.
There are only 14 possible three-dimensional lattices.
These are called Bravais' lattices..
What is crystal structure crystallography?
A crystal structure is defined as the particular repeating arrangement of atoms (molecules or ions) throughout a crystal.
Structure refers to the internal arrangement of particles and not the external appearance of the crystal..
What is the crystal structure of NaCl Mcq?
The structure of sodium chloride is face centred cubic.
Radius ratio of NaCl crystal is 0.532..
Which axis system is being satisfied by the hexagonal crystal system?
The hexagonal system has four crystallographic axes consisting of three equal horizontal, or equilateral axes at 120 degrees to each other, as well as one vertical axis which is perpendicular to the other three.
This vertical axis can be longer or shorter than the horizontal axes..
Which metal from the following has non crystalline structure?
Amorphous metals are non-crystalline, and have a glass-like structure.
But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity and can show metallic luster..
Which of the following is least symmetrical?
Triclinic, monoclinic, tetragonal refers to one of the seven crystal systems.
The most symmetrical one is the cubic system and the least symmetrical is the triclinic one..
- The structure of sodium chloride is face centred cubic.
Radius ratio of NaCl crystal is 0.532.
