elements of group dynamics

In the case of these elements, all shells except the outermost shell are completely filled. Elements belonging to I A, II A, III A, IV A, V A, VI A and VII A are normal elements. Elements of the second period are known as typical elements [Li (Z = ..

'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..

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..

As we move down a group the atomic size and nuclear size increases. As the effect of increase in atomic size is more pronounced the additional electron feels less attracted by the large atom. Consequently the electron affinity decreases. However there are some irregularities observed in ..

It is quite evident that carbon displays a great propensity in forming a large variety of carbon and hydrogen compounds. But carbon can also form bonds with other elements in a hydrocarbon chain, when one or more hydrogen is replaced by an element like oxygen, nitrogen, sulphur..

Mendeleev's Periodic table simplified the study of elements. It became useful in studying and remembering the properties of a large number of elements, in a simpler way. This is because the elements showing similar properties belonged to the same group..

a) Oxygen and water (air dissolved in water) b) Oxygen, nitrogen, carbon dioxide and water vapour (air). Mixtures can also be grouped on the basis of their physical state..

Introduction - The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This block includes the elements of..

Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations. ..

The modern periodic table is based on the electronic configuration of the elements. The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact with other atoms and take part in all chemical reactions, while..
