Consider an ideal FCC crystal system, which is fully occupied by the particles A , B and C , which are present at lattice points, octahedral voids and tetrahedral voids respectively. Identify the correct statement.

Options

  1. AParticle B is surrounded by 8 particles of C at a distance approximately equal a 3 4
  2. BFigure represents one of the plane of symmetry
  3. CFigure represents one of the plane of symmetry
  4. D1^ st nearest neighbour of particle A is 8 particles of C and 2^ nd nearest neighbour is 6 particles of B

Correct answer

D. 1^ st nearest neighbour of particle A is 8 particles of C and 2^ nd nearest neighbour is 6 particles of B

Step-by-step solution

O . V . is surrounded by 8 ~T . V . One particle of A is surrounded by 8 ~T . V . and also surrounded by 6 O.V.
