Final answer:
No, the lattice of an element with face-centered cubic (FCC) crystal structure cannot be regarded as simple cubic (SC). The FCC unit cell consists of atoms at all of the corners and at the centers of each face, while in simple cubic (SC), there is only one atom positioned at each lattice point.
Step-by-step explanation:
No, the lattice of an element with face-centered cubic (FCC) crystal structure cannot be regarded as simple cubic (SC).
The FCC unit cell consists of atoms at all of the corners and at the centers of each face. It contains four atoms: one-eighth of an atom at each of the eight corners and one-half of an atom on each of the six faces. The atoms at the corners touch the atoms in the centers of the adjacent faces along the face diagonals of the cube. This arrangement is not the same as a simple cubic lattice.
In simple cubic (SC) lattice, there is only one atom positioned at each lattice point. It has an atom at each corner of the unit cell, with no atoms on the faces or inside the unit cell.
