the contribution of an atom when it is placed at the centre of the edge in a unit cell of a cube is
Answers
Answer:
For an atom at the edge centre: An edge of the cubic unit cell is always shared between 4 unit cells. Hence an atom at the edge centre will be shared between 4 unit cells and its contribution to one unit cell will be 14.
The contribution of a particle always depends on the number of unit cells it is being shared with, which depends on its position. An edge of a cubic unit cell is common between 4 different unit cells.

Basically a unit cell is the smallest repeating unit of a crystal lattice or we can say that building block of the crystal. And the arrangement in 3D form of the atoms, molecules and ions inside of any crystal is known as a crystal lattice. Many unit cells combine together to form a crystal lattice. Each lattice point is occupied by an atom, molecules or an ion.
Each lattice point is occupied by an atom, molecules or an ion. Based on these arrangement there are 3 types of unit cells:
Each lattice point is occupied by an atom, molecules or an ion. Based on these arrangement there are 3 types of unit cells:(1) Primitive cubic unit cell: In this atoms are present at all the corners of the unit cell. (2) Body-centered cubic unit cell: In this atoms are present at the corners as well as the body centre of the unit cell.
