How Many Atoms are Present in the End Centred Cubic Unit Cell?
In the crystal lattice, an end-centred unit cell exists. The location of component particles can be used to determine the number of atoms. Look into the 8 corners and two opposing faces of a cube towards the conclusion, keeping your gaze focused.
Step-by-step instructions are as follows:
Let us begin by discussing the unit cell. The crystal structure is made up of many unit cells, as we already know.
This type & location of component elements can now be used to estimate the number of atoms, ions, or molecules in such a unit cell.
The primitive cubic, body-centred cubic, face-centred cubic, and end-centred cubic unit cells may all be seen.
When it comes to the end-centred cubic unit cell, 8 atoms are placed on each of the cube’s eight corners, and 1 atom is placed on each of the cube’s two opposing faces.
As a result, if eight atoms are present in each of the eight corners, each atom will contribute one-eighth of the total.
As a result, 8×18=1 atom
Now, if two atoms are on opposing sides of the face, each contributes a 12th share.
Thus, 2×12=1 atom.
so, the total number of atoms present is 2
Don’t get mixed up with the many sorts of unit cells. Simply apply the phrase to the cube’s corners and opposing faces, or the atoms present at the cell’s centre, in the end-centred unit cell.
