The structural formula for all the octahedral complexes of [Ni(H 2 O) 3 (OH) 2 Cl] needs to be determined. Concept introduction: Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands. The chemical and physical properties of the complex ions and the coordination compounds formed by them depend on the spatial arrangement of ligands which are attached directly to the central metal atom.

Question

In the initial linear section of the stress-strain curve of a metal or alloy. Explain from the point of view of atomic structure?(a) No, the atomic level properties of the material can never be related to the linear section.(b) The elastic zone is influenced by the strength of the bonds between atoms.(c) The stronger the bond, the less rigid and the lower the Young's Modulus of the material tested.(d) The stronger the bond, the less stress is necessary to apply to the material to deform it elastically.
