Physical Characteristics Group 16 Elements - The important physical properties of the elements of group 16 are recorded as shown below: Some physical properties of the elements of group 16 Property Oxygen Sulphur Selenium Tellurium Poloniu..

Property Oxygen Sulphur Selenium Tellurium Polonium Atomic radius (A o ) 0.73 1.09 1.16 1.35 - Ionic (M 2+ ) radius (A o ) 1.40 1.85 1.98 2.21 Ionization energy (kJ mol -1 ) 1314 1000 941 869 - ..

The first ionization energies of group 13 elements are less than the corresponding members of the alkaline earths. Explanation: The first electron in the case of group 13 elements (ns 2 np 1 ) is to be removed from p-orbital whi..

Grouping of Elements - In the long form of the periodic table, elements are grouped into four main blocks, purely on the basis of electronic configurations. Elements are grouped in blocks 's', 'p', 'd' and 'f' depending on the nature of or..

The important physical constants of group 13 elements arc given in table and their physical characteristics are discussed below: B Al Ga In Tl Atomic radius (pm) 85 143 135 167 170 Ionic radius (pm) M 3+ 27 53.5 62.0 80.0 88.5 Densi..

Similar physical and chemical properties are shown by elements in a group. However the first member of each group differs from its succeeding members (called congeners). This mainly occurs because of, The small size of the atom and its ion. The high ionizati..

These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging t..

The first ionization energies of the group 15 elements are higher than the corresponding members of the group 14 elements. Explanation: The larger ionization energy is due to greater nuclear charge, small size and stab..

Alkali metals have the lowest ionization energy in each period. Within the group, as we go down, the ionization energies of alkali metals decrease due to their atomic size being the largest in their respective periods. In large atoms the valence e..

Elements - "An element is a pure substance which is made up of only one kind of atoms having the same atomic number." "The smallest particle of an element is the atom which, has all the properties of that element." "An element..
