In bcc structure contribution of corner and central atom is-

Write the structure and the hybridisation of the central atom in [Ni(CO)_4]

Statement -1 In HCP structure the contribution of hexagonal face corner per atom is 1/12 Statement -2 it is shared by 6 different unit cells

Write the structure and hybridisation of the central atom in [CoCl_2 (NH_3)_4]

Assertion : A metal crystallizing in bcc structure has coordination number of eight. Reason : Each metal atom at the corner is surrounded by eight body centred atoms.

In any cubic system, the contribution of the atom at the corner is

In a cubic close packed structure, fractional contributions of an atom at the corner and at the face in the unit cell are, respectively-
