Why a covalent bond is directional?
Covalent bond is formed as a result of pairing of two electrons in atomic orbitals of two atoms. Bond then must lie along the direction of atomic orbital i.e. bond only takes place in the direction of shared pairs of electrons. Hence covalent bonds would have strong directional preferences unlike metallic and ionic bonds.
Explain the following observations: (i) Generally there is an increase in density of elements from titanium (Z = 22) to copper (z =29) in the first series of transition element
The effects that temperature has on the equilibrium position of a reaction can also be explained by using Le Chtelier's Principle. Recall that in an exothermic reaction, heat i
