Gallium, indium and thallium are less abundant elements in nature.Consequently, a lot of variation in properties of elements in a group of p-block is observed.These two groups of elements have high negative electron gain enthalpies and readily add one or two electrons respectively to attain the stable noble gas configureuration.According to Freud's theory, the primary structural elements of personality are three, i.e. id, ego, and superego.In contrast, the third period elements of p-groups with the electronic configureuration 3s23pn have the vacant 3d orbitals lying between the 3p and the 4s levels of energy.According to him, the material world was made up of four elements, viz.By 1829 he noted a similarity among the physical and chemical properties of several groups of three elements (Triads).A modern version, the so-called long form of the Periodic Table of the elements (Figureure 2), is the most convenient and widely used.The permanent name might reflect the country (or state of the country) in which the element was discovered.Within each series, the properties of the elements are quite similar.The new elements with very high atomic numbers are so unstable that only minute quantities, sometimes only a few atoms of them are obtained.The tri-chlorides, bromides and iodides of all these elements being covalent in nature are hydrolysed in water.Abraham Maslow, a well-known Psychologist in a classic paper published in 1943, outlined the elements of an overall theory of motivation.What are the reasons for the different chemical behaviour of the first member of a group of elements in the s- and p-blocks compared to that of the subsequent members in the same group? The anomalous behaviour is attributed to their small size, large charge/ radius ratio and high electronegativity of the elements.The relative stability of +1 oxidation state progressively increases for heavier elements: Al
