The two elements which show similarities in their properties can be called a diagonal pair or diagonal neighbours. For example, Lithium of group 1A and second period shows similarities with the properties of magnesium which are located in the 2nd group and 3rd period. The anomaly of these elements is due to their, ⇒ Check: Preparation and properties of hydrogen peroxide. Calcium, the s – block element preceding the first row of transition elements, has the electronic structure. The first transition series involves the filling of 3d orbitals. Smaller the size of the ion the hydration enthalpy is high as the atom has the capacity to accommodate a larger number of water molecules around it due to high charge/radius ratio and hence gets hydrated. It starts from scandium (Z = 21) and goes up to zinc (Z = 30).

The alkali metals have a low melting and boiling point due to the. Alkali metals and its respective salts have the capability to impart colour to the oxidizing flame due to the heat generated from the flame which excites the valence electrons from one energy level to another energy level. The elements of group 12 i.e., Zinc, Cadmium, and Mercury are generally not regarded as transition elements as their atoms and all ions formed have completely filled d-orbitals i.e., these do not have partially filled d-orbitals in atomic state or common oxidation state (Zn 2+ , Cd 2+ , Hg 2+ ).
