Calculate the number of atoms belong to one unit cell of simple cubic unit cell(sc) |
|
Answer» Solution :(i) In the simple cubic unit CELL, each comer is occupied by an identical atoms (or) IONS (or) molecules and they touch along the edges of CUBE, do not touch diagonally. The coordination number of cach atom is 6. (ii) Each atom in the corner of the cubic unit cell is shared by 8 neighbouring unit cells and THEREFORE atoms per unit cell is equal to `(N_(c))/(8)`. where Nc is the number of atoms at the CORNERS. (iii) `:.` no of atoms in a SC unit cell `=((N_(c))/(8))=((8)/(8))=1`
