element tables

The elements of s and p-block of the periodic table are collectively called representative 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 orbital(s) into which the last electron of the atom ent..

On the basis of electronic configuration, the elements of the periodic table are classified into: (1) Noble gases, (2) Normal elements, (3) Transition elements, (4) Inner-transition elements, (5) Alkali metals and (6) Halogen..

On the basis of electronic configuration, the elements of the periodic table are classified into: (1) Noble gases, (2) Normal elements, (3) Transition elements, (4) Inner-transition elements, (5) Alkali metals and (6) Halogen..

'd' block elements are called transition elements. These elements occupy groups 3 to 12 on the periodic table. There are four series of transitional elements, '3d', '4d', '5d' and '6d' depending on the energy levels of 'd' orbitals. They have a gen..

Electronic Configurations of Atoms - Based upon the rules and sequence of energy levels, one can write the electronic configurations of atoms of some rows of the periodic table..

The third row elements are from sodium to argon. The build up of these eight elements proceeds exactly in the same manner as discussed above. Here 3s- and 3p-orbitals are filled in place of 2s- and 2p-orbitals as has been done in case of Li to Ne. For e.g., the electronic conf..

Symbol: C Atomic number : 6 Atomic mass: 12 (most common isotope) Electronic configuration: 1s 2 ,2s 2 ,2p 2 Position in the periodic table: Period II Group IV Carbon occurs in the free state as well as combined state. The following schematic chart shows the occurrence of carbon in va..

Mendeleev's Periodic table simplified the study of elements. As the arrangements of elements showing similar properties were classified into groups, it was very useful in studying and remembering the properties of a large number of elements in a systematic w..

Introduction - With the rapid development of Chemistry and the discovery of new elements, it was necessary to develop a simple way to study and remember the numerous properties of the elements and their compounds. This gave rise to the necessity of classification of the ele..
