How many atoms can be present in a simple cubic lattice ?

Explanation

(i) In a simple cubic lattic atoms are present at the corner only, each atom at the corner is shared equally by eight other unit cells.
(ii) The total number of atoms per unit cell `= ( N_(c ))/( 8) = 8 xx (1)/( 8) = 1 ` ( `N_( c )` is the number of atoms at the corner. )
