The elements lying between s and p-block of periodic table that constitute a large block of elements are called transition elements. These elements have partly field (n-1)d orbital. Since last electron fill into d-orbital, so they are called transition elements or d-block elements. They show transitional behavior.

The f- block (inner transition) elements containing partially filled 4f-subshells are known as Lanthanides or Lanthanones because of their close similarities with element lanthanum (atomic no: 57). The fourteen elements from atomic no: 58 to 71 constitute lanthanides.

Electrochemistry is a branch of chemistry which deals with inter-conversion of chemical energies and electrical energy. We’ll discuss electrolytic reactions (reactions that occur when electricity passes through solutions) as well as electromagnetic reaction (reactions that produce electric energy). Some examples of electrolytic reactions are electrolysis, electroplating, electro refining of metals, etc. Some examples of electro genetic reactions are reactions occurring in cells or batteries.

Coordination compounds are those addition molecular compounds which retain their identity in solid state as well as in dissolved state. In these compounds. the central metal atom or ion is linked by ions or molecules with coordinate bonds. e.g., Potassium ferrocyanide, K4 [Fe(CN)6]

Process: Melting of a crystalline solid attains equilibrium under 1 atmospheric pressure at a certain temperature, wherein the temperature is termed as the melting or freezing point of that solid. Changes: On application of constant heat to the equilibrium mixture, solid gets converted to liquid. But if the mixture is kept in an insulated thermos flask, a dynamic equilibrium, (i.e. both the states would be constant) would be maintained

The topic for the last part of our physics class this quarter will be thermodynam- ics. Thermodynamics deals with energy transfer processes. The key idea is that materials have ”internal energy”. The internal energy is the energy that the atoms and molecules of the material possess. For example, in a gas and liquid the molecules are moving and have kinetic energy. The molecules can also rotate and vibrate, and these motions also contribute to the gases total internal energy. In a solid, the ...
