Concept introduction:
Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions
Ligand field theory: It is used to explain the bonding between metal and ligand in a coordination complex. Ligand field theory is explained in terms of electrostatic interaction of between metal ion and ligands.
Electronic configuration shows the electrons distribution of atoms or molecule in its molecular or atomic orbitals. The electrons are distributed in orbitals by following three important rules, Aufbau's Principle, Pauli-exclusion principle, and Hund's Rule.
If the complex has minimum one unpaired electron, then they are paramagnetic and are attracted towards the magnetic field. If all the electrons are paired in a complex, then they are diamagnetic and are repelled from the magnetic field.
Equation for density is,

Chemistry & Chemical Reactivity
- Different substances containing the same transition metal often demonstrate a wide range of colors. Elemental copper is reddish-brown, for example, while copper(I) chloride is white and copper(II) carbonate is blue-green. Why is it that complexes of one transition metal can have many colors? Select one: The color of a substance changes based on the number of chemical reactions it goes through. The particle size of a substance affects its appearance. Transition metal complexes are particularly sensitive to the quality of preparation and presence of impurities. Transition metals are influenced by the presence and nature of any anions.arrow_forwardA 67.2 g sample of gold and palladium allo contains 3.40x10^23 atoms.

The common oxidation number for an alkaline earth metal is +2. (a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol. (b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy change for the reaction below.

- A nonmetal element in the third row of the periodic table exists as two allotropes (two different physical forms of the same element). One allotrope exists as an extended network while the other exists as discrete molecules. In the lab, you gather the following evidence about two allotropes of this element: Physical Form of Element Melting Point Allotrope 1 Allotrope 2 03 Which allotrope do you predict likely exists as an extended network and why? 1. Allotrope 2 because strong covalent bonds within the molecule require a lot of energy to break when melting a substance from a solid to a liquid. 2. Allotrope 1 because small molecules require less energy due to the weaker interactions to overcome compared to breaking strong covalent bonds when an extended network melts (essentially disintegrating). 3. Allotrope 1 because its lower melting point suggests that it makes a good liquid. 4. The data is wrong as all allotropes of the same element must have the same properties. 5.
