b) B.C.C.

c) E.C.C.​

Answer 1

in the body centeret unit cell,there is one atom or ion in the centeret of the unit cell is addition to the corner atoms or ions. pay special attention to the last diagram of each type of cell. you will notice that the atoms or ions at the edges of each face or at the corners are not complete spheres hi

Answer 2

Explanation:

body-centered cubic: There is one atom or ion in the center of the unit cell in addition to the corner atoms or ions. face-centered cubic: There are also atoms or ions in the center of each of the six faces of the unit cell. simple cubic: The atoms or ions are at the corners of the unit cell only.
