GEOLOGY

Detailed explanation-1: -In a simple cubic unit cell since each cubic unit cell has 8 atoms on its corners.

Detailed explanation-2: -Ans-The simple cubic unit cell consists of eight atoms, which outline the cube itself. These are corner atoms, so each contributes only one-eighth of an atom to the unit cell, resulting in a total of one atom.

Detailed explanation-3: -A compound mode up of element A and B crystallites in a cubic structure. Atoms A are present on the corners as well as face-centres, whereas atom B are present on the edge-centres as well as body-centre.

Detailed explanation-4: -A cubic unit cell has one atom on each corner and one atom on each body diagonal.

Detailed explanation-5: -The corners contribute only one net atom and the center atom contributes another for a total of two net atoms. Please, notice that the corner atoms are not touching one another. Instead, the atoms touch through the center atom along the diagonal of the cube.
