Question

write about the Primitive or simple cubic unit cell (sc) ​

Answer 1

Answer:

Primitive or simple cubic unit cell (sc) :

A simple cubic cell has particles at its eight corners. When these unit cells are stacked together, particle at each corner of a given unit cell is shared with seven other neighbouring cubes that come together at that corner. As a result the corner particle contributes its 1/8^th part to the given unit cell. Thus, a simple cubic cell has 1/8 × 8 = 1 particle per unit cell.

Answer 2

Answer:

The primitive cubic system (cP) consists of one lattice point on each corner of the cube. Each atom at a lattice point is then shared equally between eight adjacent cubes, and the unit cell therefore contains in total one atom (1⁄8 × 8).
