Question

3: The coordination no. of Y will be in the XY types of crystal: A 6 B 8 C 12 D 4​ the answer is 6 how it came

Answer 1

Explanation:

Co-ordination number is the number of spheres (atoms, molecules or ions) directly surrounding a single sphere in a crystal. The coordination number in a face centered cubic close packing structure is 12

Answer 2

Its come because the coordination number in crystals is found by counting the number of neighboring atoms. Most commonly, the coordination number looks at an atom in the interior of a lattice, with neighbors extending in all directions.

So the coordination no. of Y will be in the XY types of crystal is 6
