family of elements in the periodic elements

Periodicity of Elements - The recurrence of similar properties of the elements when they are arranged in the order of increasing atomic number, after certain regular intervals, is called periodicity..

Group 15 of the Periodic table includes five elements namely nitrogen (N), phosphorus (P), arsenic (As) antimony (Sb) and bismuth (Bi). This group is regarded as nitrogen family. There is a transition from non-metallic to metallic character as we go down the group. Nit..

Carbon (C), silicon (Si), germanium (Ge), tin (Sn) and lead (Pb) constitute the group 14 of the periodic table. This group is known as carbon family..

Group 13 of the periodic table consists of the elements boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl). Except boron, which is classified as a non-metal, all other elements of this group are meta..

Group 17 of the periodic table contains the elements fluorine, chlorine, bromine, iodine and astatine. These elements are collectively known as the HALOGENS. This name is derived from two Greek words Halo and Gens meaning 'salt producing'. Halogens are among the ..

Position of Elements in the Modern Periodic Table - Types of Elements On the basis of electronic configuration, the elements of the periodic table are classified into: Noble gases Normal elements Transition elements Inner-transit..

Cause of Periodicity of Elements - 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..

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 reacti..

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..
