The lattice site in a pure crystal cannot be occupied by ………. .

Options

A. Molecule
B. Ion
C. Electron
D. Atom

Answer

C

Explanation

Each point in a lattice is known as lattice points which can be either atom, molecule or ion. It is joined together by a straight line to bring out geometry of lattice in pure crystal constituents. They are arranged in fixed stoichiometric ratio. Hence, existence of free electrons are not possible.
